Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532750, here are decompositions:

13 + 31532737 = 31532750
97 + 31532653 = 31532750
157 + 31532593 = 31532750
163 + 31532587 = 31532750
199 + 31532551 = 31532750
211 + 31532539 = 31532750
229 + 31532521 = 31532750
313 + 31532437 = 31532750

Showing the first eight; more decompositions exist.
