Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102988, here are decompositions:
- 5 + 102983 = 102988
- 59 + 102929 = 102988
- 107 + 102881 = 102988
- 191 + 102797 = 102988
- 227 + 102761 = 102988
- 311 + 102677 = 102988
- 401 + 102587 = 102988
- 449 + 102539 = 102988
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 102,988 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
