Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497016, here are decompositions:

  • 53 + 31496963 = 31497016
  • 59 + 31496957 = 31497016
  • 197 + 31496819 = 31497016
  • 233 + 31496783 = 31497016
  • 347 + 31496669 = 31497016
  • 443 + 31496573 = 31497016
  • 449 + 31496567 = 31497016
  • 479 + 31496537 = 31497016

Showing the first eight; more decompositions exist.
