Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538208, here are decompositions:

  • 7 + 538201 = 538208
  • 61 + 538147 = 538208
  • 157 + 538051 = 538208
  • 331 + 537877 = 538208
  • 367 + 537841 = 538208
  • 397 + 537811 = 538208
  • 421 + 537787 = 538208
  • 439 + 537769 = 538208

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 538,208 and was likely granted around 1894.

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