Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620140, here are decompositions:

  • 7 + 8620133 = 8620140
  • 19 + 8620121 = 8620140
  • 29 + 8620111 = 8620140
  • 31 + 8620109 = 8620140
  • 71 + 8620069 = 8620140
  • 97 + 8620043 = 8620140
  • 197 + 8619943 = 8620140
  • 257 + 8619883 = 8620140

Showing the first eight; more decompositions exist.
