Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697818, here are decompositions:

  • 7 + 8697811 = 8697818
  • 127 + 8697691 = 8697818
  • 211 + 8697607 = 8697818
  • 307 + 8697511 = 8697818
  • 439 + 8697379 = 8697818
  • 541 + 8697277 = 8697818
  • 691 + 8697127 = 8697818
  • 757 + 8697061 = 8697818

Showing the first eight; more decompositions exist.
