Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31509594, here are decompositions:

23 + 31509571 = 31509594
37 + 31509557 = 31509594
41 + 31509553 = 31509594
71 + 31509523 = 31509594
107 + 31509487 = 31509594
163 + 31509431 = 31509594
191 + 31509403 = 31509594
223 + 31509371 = 31509594

Showing the first eight; more decompositions exist.
