Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474762, here are decompositions:

29 + 31474733 = 31474762
41 + 31474721 = 31474762
71 + 31474691 = 31474762
89 + 31474673 = 31474762
191 + 31474571 = 31474762
281 + 31474481 = 31474762
359 + 31474403 = 31474762
419 + 31474343 = 31474762

Showing the first eight; more decompositions exist.
