Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592974, here are decompositions:

3 + 31592971 = 31592974
53 + 31592921 = 31592974
131 + 31592843 = 31592974
227 + 31592747 = 31592974
311 + 31592663 = 31592974
353 + 31592621 = 31592974
443 + 31592531 = 31592974
521 + 31592453 = 31592974

Showing the first eight; more decompositions exist.
