Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597632, here are decompositions:

19 + 31597613 = 31597632
29 + 31597603 = 31597632
61 + 31597571 = 31597632
83 + 31597549 = 31597632
139 + 31597493 = 31597632
149 + 31597483 = 31597632
179 + 31597453 = 31597632
349 + 31597283 = 31597632

Showing the first eight; more decompositions exist.
