Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 108072, here are decompositions:
- 11 + 108061 = 108072
- 31 + 108041 = 108072
- 59 + 108013 = 108072
- 61 + 108011 = 108072
- 73 + 107999 = 108072
- 101 + 107971 = 108072
- 131 + 107941 = 108072
- 149 + 107923 = 108072
Showing the first eight; more decompositions exist.
As an unsigned 32-bit integer, this is the IPv4 address 0.1.166.40.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 108,072 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 108072 first appears in π at position 79,465 of the decimal expansion (the 79,465ordinal-suffix:th digit after the integer 3).
Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
