Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690906, here are decompositions:

  • 79 + 8690827 = 8690906
  • 109 + 8690797 = 8690906
  • 139 + 8690767 = 8690906
  • 193 + 8690713 = 8690906
  • 223 + 8690683 = 8690906
  • 229 + 8690677 = 8690906
  • 307 + 8690599 = 8690906
  • 313 + 8690593 = 8690906

Showing the first eight; more decompositions exist.
