Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484564, here are decompositions:

31 + 31484533 = 31484564
61 + 31484503 = 31484564
103 + 31484461 = 31484564
151 + 31484413 = 31484564
211 + 31484353 = 31484564
283 + 31484281 = 31484564
421 + 31484143 = 31484564
607 + 31483957 = 31484564

Showing the first eight; more decompositions exist.
