Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612798, here are decompositions:

59 + 31612739 = 31612798
71 + 31612727 = 31612798
131 + 31612667 = 31612798
137 + 31612661 = 31612798
179 + 31612619 = 31612798
251 + 31612547 = 31612798
311 + 31612487 = 31612798
317 + 31612481 = 31612798

Showing the first eight; more decompositions exist.
