Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484364, here are decompositions:

5 + 31484359 = 31484364
11 + 31484353 = 31484364
47 + 31484317 = 31484364
61 + 31484303 = 31484364
83 + 31484281 = 31484364
97 + 31484267 = 31484364
127 + 31484237 = 31484364
157 + 31484207 = 31484364

Showing the first eight; more decompositions exist.
