Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465126, here are decompositions:

3 + 31465123 = 31465126
179 + 31464947 = 31465126
317 + 31464809 = 31465126
509 + 31464617 = 31465126
569 + 31464557 = 31465126
617 + 31464509 = 31465126
683 + 31464443 = 31465126
857 + 31464269 = 31465126

Showing the first eight; more decompositions exist.
