Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742944, here are decompositions:

  • 3 + 8742941 = 8742944
  • 13 + 8742931 = 8742944
  • 97 + 8742847 = 8742944
  • 127 + 8742817 = 8742944
  • 157 + 8742787 = 8742944
  • 271 + 8742673 = 8742944
  • 307 + 8742637 = 8742944
  • 367 + 8742577 = 8742944

Showing the first eight; more decompositions exist.
