Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559414, here are decompositions:

13 + 31559401 = 31559414
31 + 31559383 = 31559414
43 + 31559371 = 31559414
97 + 31559317 = 31559414
151 + 31559263 = 31559414
163 + 31559251 = 31559414
283 + 31559131 = 31559414
421 + 31558993 = 31559414

Showing the first eight; more decompositions exist.
