Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532594, here are decompositions:

7 + 31532587 = 31532594
13 + 31532581 = 31532594
43 + 31532551 = 31532594
73 + 31532521 = 31532594
97 + 31532497 = 31532594
157 + 31532437 = 31532594
193 + 31532401 = 31532594
241 + 31532353 = 31532594

Showing the first eight; more decompositions exist.
