Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535424, here are decompositions:

  • 5 + 31535419 = 31535424
  • 7 + 31535417 = 31535424
  • 13 + 31535411 = 31535424
  • 43 + 31535381 = 31535424
  • 47 + 31535377 = 31535424
  • 83 + 31535341 = 31535424
  • 97 + 31535327 = 31535424
  • 103 + 31535321 = 31535424

Showing the first eight; more decompositions exist.
