Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618940, here are decompositions:

  • 7 + 8618933 = 8618940
  • 17 + 8618923 = 8618940
  • 23 + 8618917 = 8618940
  • 47 + 8618893 = 8618940
  • 61 + 8618879 = 8618940
  • 73 + 8618867 = 8618940
  • 79 + 8618861 = 8618940
  • 89 + 8618851 = 8618940

Showing the first eight; more decompositions exist.
