Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475974, here are decompositions:

11 + 31475963 = 31475974
197 + 31475777 = 31475974
293 + 31475681 = 31475974
503 + 31475471 = 31475974
521 + 31475453 = 31475974
587 + 31475387 = 31475974
653 + 31475321 = 31475974
743 + 31475231 = 31475974

Showing the first eight; more decompositions exist.
