Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484700, here are decompositions:

  • 53 + 31484647 = 31484700
  • 73 + 31484627 = 31484700
  • 83 + 31484617 = 31484700
  • 131 + 31484569 = 31484700
  • 157 + 31484543 = 31484700
  • 167 + 31484533 = 31484700
  • 197 + 31484503 = 31484700
  • 239 + 31484461 = 31484700

Showing the first eight; more decompositions exist.
