Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612864, here are decompositions:

  • 3 + 8612861 = 8612864
  • 97 + 8612767 = 8612864
  • 151 + 8612713 = 8612864
  • 157 + 8612707 = 8612864
  • 163 + 8612701 = 8612864
  • 181 + 8612683 = 8612864
  • 193 + 8612671 = 8612864
  • 223 + 8612641 = 8612864

Showing the first eight; more decompositions exist.
