Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527596, here are decompositions:

13 + 31527583 = 31527596
19 + 31527577 = 31527596
73 + 31527523 = 31527596
97 + 31527499 = 31527596
349 + 31527247 = 31527596
439 + 31527157 = 31527596
487 + 31527109 = 31527596
643 + 31526953 = 31527596

Showing the first eight; more decompositions exist.
