Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657042, here are decompositions:

  • 103 + 8656939 = 8657042
  • 109 + 8656933 = 8657042
  • 139 + 8656903 = 8657042
  • 151 + 8656891 = 8657042
  • 193 + 8656849 = 8657042
  • 211 + 8656831 = 8657042
  • 241 + 8656801 = 8657042
  • 283 + 8656759 = 8657042

Showing the first eight; more decompositions exist.
