Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509390, here are decompositions:

  • 31 + 509359 = 509390
  • 61 + 509329 = 509390
  • 73 + 509317 = 509390
  • 97 + 509293 = 509390
  • 103 + 509287 = 509390
  • 109 + 509281 = 509390
  • 127 + 509263 = 509390
  • 151 + 509239 = 509390

Showing the first eight; more decompositions exist.
