Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8635890, here are decompositions:

  • 7 + 8635883 = 8635890
  • 23 + 8635867 = 8635890
  • 37 + 8635853 = 8635890
  • 41 + 8635849 = 8635890
  • 73 + 8635817 = 8635890
  • 79 + 8635811 = 8635890
  • 113 + 8635777 = 8635890
  • 167 + 8635723 = 8635890

Showing the first eight; more decompositions exist.
