Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 124072, here are decompositions:
- 5 + 124067 = 124072
- 71 + 124001 = 124072
- 83 + 123989 = 124072
- 89 + 123983 = 124072
- 131 + 123941 = 124072
- 149 + 123923 = 124072
- 239 + 123833 = 124072
- 251 + 123821 = 124072
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 124,072 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 124072 first appears in π at position 152,179 of the decimal expansion (the 152,179ordinal-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.
