Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525762, here are decompositions:

  • 113 + 31525649 = 31525762
  • 173 + 31525589 = 31525762
  • 263 + 31525499 = 31525762
  • 383 + 31525379 = 31525762
  • 419 + 31525343 = 31525762
  • 431 + 31525331 = 31525762
  • 479 + 31525283 = 31525762
  • 599 + 31525163 = 31525762

Showing the first eight; more decompositions exist.
