Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527454, here are decompositions:

  • 41 + 31527413 = 31527454
  • 47 + 31527407 = 31527454
  • 131 + 31527323 = 31527454
  • 137 + 31527317 = 31527454
  • 263 + 31527191 = 31527454
  • 281 + 31527173 = 31527454
  • 311 + 31527143 = 31527454
  • 347 + 31527107 = 31527454

Showing the first eight; more decompositions exist.
