Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103420, here are decompositions:
- 11 + 103409 = 103420
- 29 + 103391 = 103420
- 71 + 103349 = 103420
- 101 + 103319 = 103420
- 113 + 103307 = 103420
- 131 + 103289 = 103420
- 353 + 103067 = 103420
- 419 + 103001 = 103420
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 103,420 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
