Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454152, here are decompositions:

  • 3 + 31454149 = 31454152
  • 5 + 31454147 = 31454152
  • 29 + 31454123 = 31454152
  • 71 + 31454081 = 31454152
  • 269 + 31453883 = 31454152
  • 311 + 31453841 = 31454152
  • 419 + 31453733 = 31454152
  • 761 + 31453391 = 31454152

Showing the first eight; more decompositions exist.
