Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526612, here are decompositions:

  • 79 + 31526533 = 31526612
  • 109 + 31526503 = 31526612
  • 181 + 31526431 = 31526612
  • 193 + 31526419 = 31526612
  • 223 + 31526389 = 31526612
  • 241 + 31526371 = 31526612
  • 331 + 31526281 = 31526612
  • 373 + 31526239 = 31526612

Showing the first eight; more decompositions exist.
