Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506596, here are decompositions:

19 + 31506577 = 31506596
67 + 31506529 = 31506596
73 + 31506523 = 31506596
223 + 31506373 = 31506596
229 + 31506367 = 31506596
313 + 31506283 = 31506596
349 + 31506247 = 31506596
607 + 31505989 = 31506596

Showing the first eight; more decompositions exist.
