Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465102, here are decompositions:

3 + 31465099 = 31465102
41 + 31465061 = 31465102
281 + 31464821 = 31465102
293 + 31464809 = 31465102
401 + 31464701 = 31465102
521 + 31464581 = 31465102
593 + 31464509 = 31465102
659 + 31464443 = 31465102

Showing the first eight; more decompositions exist.
