Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526644, here are decompositions:

  • 11 + 31526633 = 31526644
  • 41 + 31526603 = 31526644
  • 167 + 31526477 = 31526644
  • 257 + 31526387 = 31526644
  • 293 + 31526351 = 31526644
  • 431 + 31526213 = 31526644
  • 503 + 31526141 = 31526644
  • 557 + 31526087 = 31526644

Showing the first eight; more decompositions exist.
