Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612102, here are decompositions:

23 + 31612079 = 31612102
59 + 31612043 = 31612102
89 + 31612013 = 31612102
191 + 31611911 = 31612102
233 + 31611869 = 31612102
251 + 31611851 = 31612102
383 + 31611719 = 31612102
443 + 31611659 = 31612102

Showing the first eight; more decompositions exist.
