Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630140, here are decompositions:

  • 23 + 8630117 = 8630140
  • 137 + 8630003 = 8630140
  • 179 + 8629961 = 8630140
  • 191 + 8629949 = 8630140
  • 251 + 8629889 = 8630140
  • 257 + 8629883 = 8630140
  • 293 + 8629847 = 8630140
  • 317 + 8629823 = 8630140

Showing the first eight; more decompositions exist.
