Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484664, here are decompositions:

17 + 31484647 = 31484664
37 + 31484627 = 31484664
47 + 31484617 = 31484664
131 + 31484533 = 31484664
151 + 31484513 = 31484664
251 + 31484413 = 31484664
311 + 31484353 = 31484664
347 + 31484317 = 31484664

Showing the first eight; more decompositions exist.
