Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535576, here are decompositions:

  • 73 + 31535503 = 31535576
  • 109 + 31535467 = 31535576
  • 157 + 31535419 = 31535576
  • 199 + 31535377 = 31535576
  • 313 + 31535263 = 31535576
  • 349 + 31535227 = 31535576
  • 433 + 31535143 = 31535576
  • 463 + 31535113 = 31535576

Showing the first eight; more decompositions exist.
