Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469506, here are decompositions:

59 + 31469447 = 31469506
83 + 31469423 = 31469506
149 + 31469357 = 31469506
179 + 31469327 = 31469506
227 + 31469279 = 31469506
479 + 31469027 = 31469506
587 + 31468919 = 31469506
683 + 31468823 = 31469506

Showing the first eight; more decompositions exist.
