Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532734, here are decompositions:

41 + 31532693 = 31532734
47 + 31532687 = 31532734
137 + 31532597 = 31532734
227 + 31532507 = 31532734
257 + 31532477 = 31532734
593 + 31532141 = 31532734
617 + 31532117 = 31532734
983 + 31531751 = 31532734

Showing the first eight; more decompositions exist.
