Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100772, here are decompositions:
- 3 + 100769 = 100772
- 31 + 100741 = 100772
- 73 + 100699 = 100772
- 79 + 100693 = 100772
- 103 + 100669 = 100772
- 151 + 100621 = 100772
- 163 + 100609 = 100772
- 181 + 100591 = 100772
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 100,772 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 100772 first appears in π at position 28,019 of the decimal expansion (the 28,019ordinal-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.
