Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526560, here are decompositions:

  • 71 + 31526489 = 31526560
  • 83 + 31526477 = 31526560
  • 137 + 31526423 = 31526560
  • 173 + 31526387 = 31526560
  • 347 + 31526213 = 31526560
  • 353 + 31526207 = 31526560
  • 419 + 31526141 = 31526560
  • 491 + 31526069 = 31526560

Showing the first eight; more decompositions exist.
