Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469456, here are decompositions:

13 + 31469443 = 31469456
103 + 31469353 = 31469456
157 + 31469299 = 31469456
163 + 31469293 = 31469456
313 + 31469143 = 31469456
463 + 31468993 = 31469456
607 + 31468849 = 31469456
757 + 31468699 = 31469456

Showing the first eight; more decompositions exist.
