Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100980, here are decompositions:
- 23 + 100957 = 100980
- 37 + 100943 = 100980
- 43 + 100937 = 100980
- 53 + 100927 = 100980
- 67 + 100913 = 100980
- 73 + 100907 = 100980
- 127 + 100853 = 100980
- 151 + 100829 = 100980
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 100,980 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 100980 first appears in π at position 359,851 of the decimal expansion (the 359,851ordinal-suffix:st 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.
