Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559364, here are decompositions:

13 + 31559351 = 31559364
43 + 31559321 = 31559364
47 + 31559317 = 31559364
101 + 31559263 = 31559364
113 + 31559251 = 31559364
157 + 31559207 = 31559364
233 + 31559131 = 31559364
271 + 31559093 = 31559364

Showing the first eight; more decompositions exist.
