Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103638, here are decompositions:
- 19 + 103619 = 103638
- 47 + 103591 = 103638
- 61 + 103577 = 103638
- 71 + 103567 = 103638
- 89 + 103549 = 103638
- 109 + 103529 = 103638
- 127 + 103511 = 103638
- 167 + 103471 = 103638
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 103.638 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
