Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480064, here are decompositions:

3 + 31480061 = 31480064
43 + 31480021 = 31480064
103 + 31479961 = 31480064
271 + 31479793 = 31480064
307 + 31479757 = 31480064
367 + 31479697 = 31480064
487 + 31479577 = 31480064
523 + 31479541 = 31480064

Showing the first eight; more decompositions exist.
