Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450464, here are decompositions:

13 + 31450451 = 31450464
37 + 31450427 = 31450464
41 + 31450423 = 31450464
43 + 31450421 = 31450464
53 + 31450411 = 31450464
113 + 31450351 = 31450464
151 + 31450313 = 31450464
173 + 31450291 = 31450464

Showing the first eight; more decompositions exist.
