Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611892, here are decompositions:

23 + 31611869 = 31611892
41 + 31611851 = 31611892
89 + 31611803 = 31611892
131 + 31611761 = 31611892
173 + 31611719 = 31611892
233 + 31611659 = 31611892
251 + 31611641 = 31611892
311 + 31611581 = 31611892

Showing the first eight; more decompositions exist.
