Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474528, here are decompositions:

47 + 31474481 = 31474528
131 + 31474397 = 31474528
227 + 31474301 = 31474528
311 + 31474217 = 31474528
467 + 31474061 = 31474528
521 + 31474007 = 31474528
557 + 31473971 = 31474528
641 + 31473887 = 31474528

Showing the first eight; more decompositions exist.
