Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525154, here are decompositions:

  • 127 + 31525027 = 31525154
  • 163 + 31524991 = 31525154
  • 433 + 31524721 = 31525154
  • 547 + 31524607 = 31525154
  • 613 + 31524541 = 31525154
  • 631 + 31524523 = 31525154
  • 751 + 31524403 = 31525154
  • 811 + 31524343 = 31525154

Showing the first eight; more decompositions exist.
