Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532184, here are decompositions:

  • 17 + 31532167 = 31532184
  • 43 + 31532141 = 31532184
  • 67 + 31532117 = 31532184
  • 71 + 31532113 = 31532184
  • 113 + 31532071 = 31532184
  • 163 + 31532021 = 31532184
  • 181 + 31532003 = 31532184
  • 263 + 31531921 = 31532184

Showing the first eight; more decompositions exist.
