Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597664, here are decompositions:

13 + 31597651 = 31597664
61 + 31597603 = 31597664
157 + 31597507 = 31597664
181 + 31597483 = 31597664
193 + 31597471 = 31597664
211 + 31597453 = 31597664
421 + 31597243 = 31597664
433 + 31597231 = 31597664

Showing the first eight; more decompositions exist.
