Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486464, here are decompositions:

7 + 31486457 = 31486464
11 + 31486453 = 31486464
13 + 31486451 = 31486464
41 + 31486423 = 31486464
47 + 31486417 = 31486464
71 + 31486393 = 31486464
73 + 31486391 = 31486464
127 + 31486337 = 31486464

Showing the first eight; more decompositions exist.
