Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476238, here are decompositions:

89 + 31476149 = 31476238
179 + 31476059 = 31476238
389 + 31475849 = 31476238
461 + 31475777 = 31476238
467 + 31475771 = 31476238
557 + 31475681 = 31476238
569 + 31475669 = 31476238
641 + 31475597 = 31476238

Showing the first eight; more decompositions exist.
