Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100320, here are decompositions:
- 7 + 100313 = 100320
- 23 + 100297 = 100320
- 29 + 100291 = 100320
- 41 + 100279 = 100320
- 53 + 100267 = 100320
- 83 + 100237 = 100320
- 107 + 100213 = 100320
- 113 + 100207 = 100320
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 100,320 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 100320 first appears in π at position 424,601 of the decimal expansion (the 424,601ordinal-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.
