Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8713890, here are decompositions:

  • 11 + 8713879 = 8713890
  • 23 + 8713867 = 8713890
  • 67 + 8713823 = 8713890
  • 79 + 8713811 = 8713890
  • 83 + 8713807 = 8713890
  • 109 + 8713781 = 8713890
  • 127 + 8713763 = 8713890
  • 181 + 8713709 = 8713890

Showing the first eight; more decompositions exist.
