Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612804, here are decompositions:

71 + 31612733 = 31612804
137 + 31612667 = 31612804
257 + 31612547 = 31612804
317 + 31612487 = 31612804
491 + 31612313 = 31612804
563 + 31612241 = 31612804
653 + 31612151 = 31612804
683 + 31612121 = 31612804

Showing the first eight; more decompositions exist.
