Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471038, here are decompositions:

  • 7 + 31471031 = 31471038
  • 31 + 31471007 = 31471038
  • 37 + 31471001 = 31471038
  • 41 + 31470997 = 31471038
  • 47 + 31470991 = 31471038
  • 61 + 31470977 = 31471038
  • 97 + 31470941 = 31471038
  • 127 + 31470911 = 31471038

Showing the first eight; more decompositions exist.
