Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472672, here are decompositions:

  • 3 + 31472669 = 31472672
  • 61 + 31472611 = 31472672
  • 193 + 31472479 = 31472672
  • 223 + 31472449 = 31472672
  • 313 + 31472359 = 31472672
  • 379 + 31472293 = 31472672
  • 433 + 31472239 = 31472672
  • 463 + 31472209 = 31472672

Showing the first eight; more decompositions exist.
