Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31802, here are decompositions:

  • 3 + 31799 = 31802
  • 31 + 31771 = 31802
  • 61 + 31741 = 31802
  • 73 + 31729 = 31802
  • 79 + 31723 = 31802
  • 103 + 31699 = 31802
  • 139 + 31663 = 31802
  • 229 + 31573 = 31802

Showing the first eight; more decompositions exist.
