Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545044, here are decompositions:

  • 43 + 31545001 = 31545044
  • 103 + 31544941 = 31545044
  • 331 + 31544713 = 31545044
  • 457 + 31544587 = 31545044
  • 673 + 31544371 = 31545044
  • 733 + 31544311 = 31545044
  • 823 + 31544221 = 31545044
  • 877 + 31544167 = 31545044

Showing the first eight; more decompositions exist.
