Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701940, here are decompositions:

  • 7 + 8701933 = 8701940
  • 19 + 8701921 = 8701940
  • 67 + 8701873 = 8701940
  • 127 + 8701813 = 8701940
  • 151 + 8701789 = 8701940
  • 193 + 8701747 = 8701940
  • 199 + 8701741 = 8701940
  • 211 + 8701729 = 8701940

Showing the first eight; more decompositions exist.
