Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612606, here are decompositions:

17 + 31612589 = 31612606
23 + 31612583 = 31612606
59 + 31612547 = 31612606
293 + 31612313 = 31612606
383 + 31612223 = 31612606
563 + 31612043 = 31612606
593 + 31612013 = 31612606
887 + 31611719 = 31612606

Showing the first eight; more decompositions exist.
