Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524950, here are decompositions:

  • 13 + 31524937 = 31524950
  • 157 + 31524793 = 31524950
  • 229 + 31524721 = 31524950
  • 277 + 31524673 = 31524950
  • 307 + 31524643 = 31524950
  • 409 + 31524541 = 31524950
  • 433 + 31524517 = 31524950
  • 547 + 31524403 = 31524950

Showing the first eight; more decompositions exist.
