Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511248, here are decompositions:

  • 5 + 511243 = 511248
  • 11 + 511237 = 511248
  • 37 + 511211 = 511248
  • 47 + 511201 = 511248
  • 71 + 511177 = 511248
  • 79 + 511169 = 511248
  • 97 + 511151 = 511248
  • 137 + 511111 = 511248

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 511,248 and was likely granted around 1893.

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