Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541984, here are decompositions:

  • 3 + 31541981 = 31541984
  • 7 + 31541977 = 31541984
  • 13 + 31541971 = 31541984
  • 127 + 31541857 = 31541984
  • 157 + 31541827 = 31541984
  • 223 + 31541761 = 31541984
  • 277 + 31541707 = 31541984
  • 307 + 31541677 = 31541984

Showing the first eight; more decompositions exist.
