Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559104, here are decompositions:

11 + 31559093 = 31559104
23 + 31559081 = 31559104
53 + 31559051 = 31559104
107 + 31558997 = 31559104
131 + 31558973 = 31559104
257 + 31558847 = 31559104
281 + 31558823 = 31559104
431 + 31558673 = 31559104

Showing the first eight; more decompositions exist.
