Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574488, here are decompositions:

59 + 31574429 = 31574488
191 + 31574297 = 31574488
227 + 31574261 = 31574488
389 + 31574099 = 31574488
467 + 31574021 = 31574488
521 + 31573967 = 31574488
557 + 31573931 = 31574488
641 + 31573847 = 31574488

Showing the first eight; more decompositions exist.
