Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743872, here are decompositions:

  • 19 + 8743853 = 8743872
  • 29 + 8743843 = 8743872
  • 101 + 8743771 = 8743872
  • 103 + 8743769 = 8743872
  • 139 + 8743733 = 8743872
  • 191 + 8743681 = 8743872
  • 199 + 8743673 = 8743872
  • 233 + 8743639 = 8743872

Showing the first eight; more decompositions exist.
