Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473382, here are decompositions:

  • 23 + 31473359 = 31473382
  • 131 + 31473251 = 31473382
  • 173 + 31473209 = 31473382
  • 179 + 31473203 = 31473382
  • 191 + 31473191 = 31473382
  • 419 + 31472963 = 31473382
  • 491 + 31472891 = 31473382
  • 503 + 31472879 = 31473382

Showing the first eight; more decompositions exist.
