Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 108972, here are decompositions:
- 5 + 108967 = 108972
- 11 + 108961 = 108972
- 13 + 108959 = 108972
- 23 + 108949 = 108972
- 29 + 108943 = 108972
- 43 + 108929 = 108972
- 79 + 108893 = 108972
- 89 + 108883 = 108972
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 108,972 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
