Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573596, here are decompositions:

13 + 31573583 = 31573596
37 + 31573559 = 31573596
73 + 31573523 = 31573596
83 + 31573513 = 31573596
97 + 31573499 = 31573596
233 + 31573363 = 31573596
239 + 31573357 = 31573596
317 + 31573279 = 31573596

Showing the first eight; more decompositions exist.
