Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525268, here are decompositions:

  • 7 + 31525261 = 31525268
  • 67 + 31525201 = 31525268
  • 241 + 31525027 = 31525268
  • 277 + 31524991 = 31525268
  • 331 + 31524937 = 31525268
  • 547 + 31524721 = 31525268
  • 661 + 31524607 = 31525268
  • 727 + 31524541 = 31525268

Showing the first eight; more decompositions exist.
