Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612144, here are decompositions:

23 + 31612121 = 31612144
101 + 31612043 = 31612144
131 + 31612013 = 31612144
227 + 31611917 = 31612144
233 + 31611911 = 31612144
251 + 31611893 = 31612144
293 + 31611851 = 31612144
383 + 31611761 = 31612144

Showing the first eight; more decompositions exist.
