Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612604, here are decompositions:

7 + 31612597 = 31612604
31 + 31612573 = 31612604
73 + 31612531 = 31612604
151 + 31612453 = 31612604
181 + 31612423 = 31612604
223 + 31612381 = 31612604
241 + 31612363 = 31612604
523 + 31612081 = 31612604

Showing the first eight; more decompositions exist.
