Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622890, here are decompositions:

  • 7 + 8622883 = 8622890
  • 13 + 8622877 = 8622890
  • 19 + 8622871 = 8622890
  • 37 + 8622853 = 8622890
  • 43 + 8622847 = 8622890
  • 79 + 8622811 = 8622890
  • 97 + 8622793 = 8622890
  • 109 + 8622781 = 8622890

Showing the first eight; more decompositions exist.
