Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599370, here are decompositions:

  • 17 + 31599353 = 31599370
  • 29 + 31599341 = 31599370
  • 197 + 31599173 = 31599370
  • 269 + 31599101 = 31599370
  • 311 + 31599059 = 31599370
  • 431 + 31598939 = 31599370
  • 443 + 31598927 = 31599370
  • 461 + 31598909 = 31599370

Showing the first eight; more decompositions exist.
