Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597646, here are decompositions:

7 + 31597639 = 31597646
43 + 31597603 = 31597646
97 + 31597549 = 31597646
139 + 31597507 = 31597646
163 + 31597483 = 31597646
193 + 31597453 = 31597646
229 + 31597417 = 31597646
433 + 31597213 = 31597646

Showing the first eight; more decompositions exist.
