Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 108912, here are decompositions:
- 5 + 108907 = 108912
- 19 + 108893 = 108912
- 29 + 108883 = 108912
- 31 + 108881 = 108912
- 43 + 108869 = 108912
- 109 + 108803 = 108912
- 113 + 108799 = 108912
- 151 + 108761 = 108912
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 108,912 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
