Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532938, here are decompositions:

71 + 31532867 = 31532938
251 + 31532687 = 31532938
431 + 31532507 = 31532938
449 + 31532489 = 31532938
461 + 31532477 = 31532938
509 + 31532429 = 31532938
599 + 31532339 = 31532938
659 + 31532279 = 31532938

Showing the first eight; more decompositions exist.
