Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672040, here are decompositions:

  • 37 + 8672003 = 8672040
  • 53 + 8671987 = 8672040
  • 59 + 8671981 = 8672040
  • 61 + 8671979 = 8672040
  • 73 + 8671967 = 8672040
  • 103 + 8671937 = 8672040
  • 229 + 8671811 = 8672040
  • 271 + 8671769 = 8672040

Showing the first eight; more decompositions exist.
