Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475050, here are decompositions:

41 + 31475009 = 31475050
53 + 31474997 = 31475050
317 + 31474733 = 31475050
359 + 31474691 = 31475050
449 + 31474601 = 31475050
479 + 31474571 = 31475050
491 + 31474559 = 31475050
569 + 31474481 = 31475050

Showing the first eight; more decompositions exist.
