Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528274, here are decompositions:

  • 7 + 31528267 = 31528274
  • 61 + 31528213 = 31528274
  • 67 + 31528207 = 31528274
  • 103 + 31528171 = 31528274
  • 163 + 31528111 = 31528274
  • 181 + 31528093 = 31528274
  • 277 + 31527997 = 31528274
  • 307 + 31527967 = 31528274

Showing the first eight; more decompositions exist.
