Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532774, here are decompositions:

37 + 31532737 = 31532774
181 + 31532593 = 31532774
193 + 31532581 = 31532774
223 + 31532551 = 31532774
277 + 31532497 = 31532774
337 + 31532437 = 31532774
373 + 31532401 = 31532774
421 + 31532353 = 31532774

Showing the first eight; more decompositions exist.
