Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612592, here are decompositions:

3 + 31612589 = 31612592
19 + 31612573 = 31612592
61 + 31612531 = 31612592
79 + 31612513 = 31612592
139 + 31612453 = 31612592
163 + 31612429 = 31612592
211 + 31612381 = 31612592
223 + 31612369 = 31612592

Showing the first eight; more decompositions exist.
