Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461712, here are decompositions:

  • 59 + 31461653 = 31461712
  • 71 + 31461641 = 31461712
  • 179 + 31461533 = 31461712
  • 419 + 31461293 = 31461712
  • 431 + 31461281 = 31461712
  • 521 + 31461191 = 31461712
  • 563 + 31461149 = 31461712
  • 599 + 31461113 = 31461712

Showing the first eight; more decompositions exist.
