Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475576, here are decompositions:

367 + 31475209 = 31475576
487 + 31475089 = 31475576
523 + 31475053 = 31475576
547 + 31475029 = 31475576
577 + 31474999 = 31475576
607 + 31474969 = 31475576
709 + 31474867 = 31475576
829 + 31474747 = 31475576

Showing the first eight; more decompositions exist.
