Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454692, here are decompositions:

  • 11 + 31454681 = 31454692
  • 23 + 31454669 = 31454692
  • 41 + 31454651 = 31454692
  • 179 + 31454513 = 31454692
  • 251 + 31454441 = 31454692
  • 443 + 31454249 = 31454692
  • 491 + 31454201 = 31454692
  • 569 + 31454123 = 31454692

Showing the first eight; more decompositions exist.
