Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541456, here are decompositions:

  • 7 + 31541449 = 31541456
  • 19 + 31541437 = 31541456
  • 97 + 31541359 = 31541456
  • 109 + 31541347 = 31541456
  • 223 + 31541233 = 31541456
  • 277 + 31541179 = 31541456
  • 283 + 31541173 = 31541456
  • 409 + 31541047 = 31541456

Showing the first eight; more decompositions exist.
