Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475764, here are decompositions:

83 + 31475681 = 31475764
167 + 31475597 = 31475764
293 + 31475471 = 31475764
311 + 31475453 = 31475764
443 + 31475321 = 31475764
521 + 31475243 = 31475764
653 + 31475111 = 31475764
1031 + 31474733 = 31475764

Showing the first eight; more decompositions exist.
