Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611284, here are decompositions:

13 + 31611271 = 31611284
97 + 31611187 = 31611284
157 + 31611127 = 31611284
241 + 31611043 = 31611284
373 + 31610911 = 31611284
577 + 31610707 = 31611284
643 + 31610641 = 31611284
967 + 31610317 = 31611284

Showing the first eight; more decompositions exist.
