Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 108720, here are decompositions:
- 11 + 108709 = 108720
- 13 + 108707 = 108720
- 43 + 108677 = 108720
- 71 + 108649 = 108720
- 83 + 108637 = 108720
- 89 + 108631 = 108720
- 149 + 108571 = 108720
- 163 + 108557 = 108720
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 108,720 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 108720 first appears in π at position 930,018 of the decimal expansion (the 930,018ordinal-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.
