Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670918, here are decompositions:

  • 31 + 8670887 = 8670918
  • 107 + 8670811 = 8670918
  • 127 + 8670791 = 8670918
  • 167 + 8670751 = 8670918
  • 239 + 8670679 = 8670918
  • 251 + 8670667 = 8670918
  • 281 + 8670637 = 8670918
  • 307 + 8670611 = 8670918

Showing the first eight; more decompositions exist.
