Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542084, here are decompositions:

  • 17 + 31542067 = 31542084
  • 47 + 31542037 = 31542084
  • 53 + 31542031 = 31542084
  • 61 + 31542023 = 31542084
  • 71 + 31542013 = 31542084
  • 73 + 31542011 = 31542084
  • 83 + 31542001 = 31542084
  • 103 + 31541981 = 31542084

Showing the first eight; more decompositions exist.
