Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679840, here are decompositions:

  • 73 + 8679767 = 8679840
  • 97 + 8679743 = 8679840
  • 101 + 8679739 = 8679840
  • 131 + 8679709 = 8679840
  • 163 + 8679677 = 8679840
  • 199 + 8679641 = 8679840
  • 223 + 8679617 = 8679840
  • 233 + 8679607 = 8679840

Showing the first eight; more decompositions exist.
