Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527296, here are decompositions:

  • 19 + 31527277 = 31527296
  • 43 + 31527253 = 31527296
  • 103 + 31527193 = 31527296
  • 139 + 31527157 = 31527296
  • 397 + 31526899 = 31527296
  • 433 + 31526863 = 31527296
  • 487 + 31526809 = 31527296
  • 523 + 31526773 = 31527296

Showing the first eight; more decompositions exist.
