Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528596, here are decompositions:

17 + 31528579 = 31528596
23 + 31528573 = 31528596
37 + 31528559 = 31528596
97 + 31528499 = 31528596
137 + 31528459 = 31528596
149 + 31528447 = 31528596
163 + 31528433 = 31528596
223 + 31528373 = 31528596

Showing the first eight; more decompositions exist.
