Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619942, here are decompositions:

  • 5 + 8619937 = 8619942
  • 59 + 8619883 = 8619942
  • 73 + 8619869 = 8619942
  • 83 + 8619859 = 8619942
  • 131 + 8619811 = 8619942
  • 151 + 8619791 = 8619942
  • 223 + 8619719 = 8619942
  • 229 + 8619713 = 8619942

Showing the first eight; more decompositions exist.
