Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105458, here are decompositions:

  • 61 + 105397 = 105458
  • 79 + 105379 = 105458
  • 97 + 105361 = 105458
  • 127 + 105331 = 105458
  • 139 + 105319 = 105458
  • 181 + 105277 = 105458
  • 229 + 105229 = 105458
  • 421 + 105037 = 105458

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 105,458 and was likely granted around 1870.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
