Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100426, here are decompositions:
- 23 + 100403 = 100426
- 47 + 100379 = 100426
- 83 + 100343 = 100426
- 113 + 100313 = 100426
- 233 + 100193 = 100426
- 257 + 100169 = 100426
- 317 + 100109 = 100426
- 383 + 100043 = 100426
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 100,426 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
