Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548672, here are decompositions:

13 + 31548659 = 31548672
19 + 31548653 = 31548672
31 + 31548641 = 31548672
53 + 31548619 = 31548672
59 + 31548613 = 31548672
79 + 31548593 = 31548672
109 + 31548563 = 31548672
139 + 31548533 = 31548672

Showing the first eight; more decompositions exist.
