Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532166, here are decompositions:

  • 53 + 31532113 = 31532166
  • 103 + 31532063 = 31532166
  • 163 + 31532003 = 31532166
  • 199 + 31531967 = 31532166
  • 257 + 31531909 = 31532166
  • 283 + 31531883 = 31532166
  • 349 + 31531817 = 31532166
  • 353 + 31531813 = 31532166

Showing the first eight; more decompositions exist.
