Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659920, here are decompositions:

  • 7 + 8659913 = 8659920
  • 11 + 8659909 = 8659920
  • 47 + 8659873 = 8659920
  • 53 + 8659867 = 8659920
  • 83 + 8659837 = 8659920
  • 109 + 8659811 = 8659920
  • 127 + 8659793 = 8659920
  • 151 + 8659769 = 8659920

Showing the first eight; more decompositions exist.
