Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530158, here are decompositions:

  • 61 + 31530097 = 31530158
  • 97 + 31530061 = 31530158
  • 157 + 31530001 = 31530158
  • 181 + 31529977 = 31530158
  • 277 + 31529881 = 31530158
  • 409 + 31529749 = 31530158
  • 487 + 31529671 = 31530158
  • 601 + 31529557 = 31530158

Showing the first eight; more decompositions exist.
