Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597658, here are decompositions:

7 + 31597651 = 31597658
19 + 31597639 = 31597658
109 + 31597549 = 31597658
151 + 31597507 = 31597658
241 + 31597417 = 31597658
397 + 31597261 = 31597658
577 + 31597081 = 31597658
607 + 31597051 = 31597658

Showing the first eight; more decompositions exist.
