Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612876, here are decompositions:

3 + 31612873 = 31612876
23 + 31612853 = 31612876
137 + 31612739 = 31612876
149 + 31612727 = 31612876
257 + 31612619 = 31612876
293 + 31612583 = 31612876
389 + 31612487 = 31612876
563 + 31612313 = 31612876

Showing the first eight; more decompositions exist.
