Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484370, here are decompositions:

7 + 31484363 = 31484370
11 + 31484359 = 31484370
17 + 31484353 = 31484370
31 + 31484339 = 31484370
53 + 31484317 = 31484370
67 + 31484303 = 31484370
89 + 31484281 = 31484370
103 + 31484267 = 31484370

Showing the first eight; more decompositions exist.
