Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599590, here are decompositions:

  • 37 + 31599553 = 31599590
  • 103 + 31599487 = 31599590
  • 151 + 31599439 = 31599590
  • 241 + 31599349 = 31599590
  • 277 + 31599313 = 31599590
  • 283 + 31599307 = 31599590
  • 331 + 31599259 = 31599590
  • 397 + 31599193 = 31599590

Showing the first eight; more decompositions exist.
