Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526564, here are decompositions:

  • 31 + 31526533 = 31526564
  • 37 + 31526527 = 31526564
  • 61 + 31526503 = 31526564
  • 67 + 31526497 = 31526564
  • 193 + 31526371 = 31526564
  • 283 + 31526281 = 31526564
  • 337 + 31526227 = 31526564
  • 367 + 31526197 = 31526564

Showing the first eight; more decompositions exist.
