Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31575634, here are decompositions:

  • 23 + 31575611 = 31575634
  • 71 + 31575563 = 31575634
  • 113 + 31575521 = 31575634
  • 197 + 31575437 = 31575634
  • 227 + 31575407 = 31575634
  • 257 + 31575377 = 31575634
  • 281 + 31575353 = 31575634
  • 353 + 31575281 = 31575634

Showing the first eight; more decompositions exist.
