Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612892, here are decompositions:

19 + 31612873 = 31612892
61 + 31612831 = 31612892
139 + 31612753 = 31612892
163 + 31612729 = 31612892
229 + 31612663 = 31612892
271 + 31612621 = 31612892
379 + 31612513 = 31612892
439 + 31612453 = 31612892

Showing the first eight; more decompositions exist.
