Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484712, here are decompositions:

13 + 31484699 = 31484712
179 + 31484533 = 31484712
199 + 31484513 = 31484712
251 + 31484461 = 31484712
263 + 31484449 = 31484712
349 + 31484363 = 31484712
353 + 31484359 = 31484712
359 + 31484353 = 31484712

Showing the first eight; more decompositions exist.
