Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612404, here are decompositions:

13 + 31612391 = 31612404
23 + 31612381 = 31612404
41 + 31612363 = 31612404
53 + 31612351 = 31612404
97 + 31612307 = 31612404
127 + 31612277 = 31612404
163 + 31612241 = 31612404
181 + 31612223 = 31612404

Showing the first eight; more decompositions exist.
