Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526494, here are decompositions:

  • 5 + 31526489 = 31526494
  • 17 + 31526477 = 31526494
  • 71 + 31526423 = 31526494
  • 107 + 31526387 = 31526494
  • 281 + 31526213 = 31526494
  • 353 + 31526141 = 31526494
  • 431 + 31526063 = 31526494
  • 443 + 31526051 = 31526494

Showing the first eight; more decompositions exist.
