Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559464, here are decompositions:

17 + 31559447 = 31559464
47 + 31559417 = 31559464
113 + 31559351 = 31559464
257 + 31559207 = 31559464
383 + 31559081 = 31559464
467 + 31558997 = 31559464
491 + 31558973 = 31559464
617 + 31558847 = 31559464

Showing the first eight; more decompositions exist.
