Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449082, here are decompositions:

  • 11 + 31449071 = 31449082
  • 29 + 31449053 = 31449082
  • 53 + 31449029 = 31449082
  • 173 + 31448909 = 31449082
  • 179 + 31448903 = 31449082
  • 191 + 31448891 = 31449082
  • 383 + 31448699 = 31449082
  • 389 + 31448693 = 31449082

Showing the first eight; more decompositions exist.
