Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100660, here are decompositions:
- 11 + 100649 = 100660
- 47 + 100613 = 100660
- 101 + 100559 = 100660
- 113 + 100547 = 100660
- 137 + 100523 = 100660
- 149 + 100511 = 100660
- 167 + 100493 = 100660
- 191 + 100469 = 100660
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 100,660 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 100660 first appears in π at position 250,634 of the decimal expansion (the 250,634ordinal-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.
