Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465396, here are decompositions:

5 + 31465391 = 31465396
107 + 31465289 = 31465396
173 + 31465223 = 31465396
449 + 31464947 = 31465396
569 + 31464827 = 31465396
587 + 31464809 = 31465396
839 + 31464557 = 31465396
887 + 31464509 = 31465396

Showing the first eight; more decompositions exist.
