Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690940, here are decompositions:

  • 19 + 8690921 = 8690940
  • 23 + 8690917 = 8690940
  • 73 + 8690867 = 8690940
  • 113 + 8690827 = 8690940
  • 127 + 8690813 = 8690940
  • 151 + 8690789 = 8690940
  • 157 + 8690783 = 8690940
  • 173 + 8690767 = 8690940

Showing the first eight; more decompositions exist.
