Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469744, here are decompositions:

  • 3 + 31469741 = 31469744
  • 13 + 31469731 = 31469744
  • 73 + 31469671 = 31469744
  • 157 + 31469587 = 31469744
  • 181 + 31469563 = 31469744
  • 277 + 31469467 = 31469744
  • 337 + 31469407 = 31469744
  • 421 + 31469323 = 31469744

Showing the first eight; more decompositions exist.
