Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612584, here are decompositions:

11 + 31612573 = 31612584
37 + 31612547 = 31612584
53 + 31612531 = 31612584
71 + 31612513 = 31612584
97 + 31612487 = 31612584
103 + 31612481 = 31612584
131 + 31612453 = 31612584
193 + 31612391 = 31612584

Showing the first eight; more decompositions exist.
