Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536272, here are decompositions:

  • 211 + 31536061 = 31536272
  • 223 + 31536049 = 31536272
  • 331 + 31535941 = 31536272
  • 463 + 31535809 = 31536272
  • 601 + 31535671 = 31536272
  • 769 + 31535503 = 31536272
  • 853 + 31535419 = 31536272
  • 1009 + 31535263 = 31536272

Showing the first eight; more decompositions exist.
