Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712090, here are decompositions:

  • 31 + 8712059 = 8712090
  • 61 + 8712029 = 8712090
  • 71 + 8712019 = 8712090
  • 73 + 8712017 = 8712090
  • 103 + 8711987 = 8712090
  • 137 + 8711953 = 8712090
  • 139 + 8711951 = 8712090
  • 157 + 8711933 = 8712090

Showing the first eight; more decompositions exist.
