Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626452, here are decompositions:

  • 31 + 31626421 = 31626452
  • 223 + 31626229 = 31626452
  • 373 + 31626079 = 31626452
  • 379 + 31626073 = 31626452
  • 433 + 31626019 = 31626452
  • 499 + 31625953 = 31626452
  • 541 + 31625911 = 31626452
  • 631 + 31625821 = 31626452

Showing the first eight; more decompositions exist.
