Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526398, here are decompositions:

  • 11 + 31526387 = 31526398
  • 47 + 31526351 = 31526398
  • 191 + 31526207 = 31526398
  • 257 + 31526141 = 31526398
  • 311 + 31526087 = 31526398
  • 347 + 31526051 = 31526398
  • 479 + 31525919 = 31526398
  • 509 + 31525889 = 31526398

Showing the first eight; more decompositions exist.
