Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592646, here are decompositions:

5 + 31592641 = 31592646
47 + 31592599 = 31592646
79 + 31592567 = 31592646
89 + 31592557 = 31592646
157 + 31592489 = 31592646
179 + 31592467 = 31592646
193 + 31592453 = 31592646
199 + 31592447 = 31592646

Showing the first eight; more decompositions exist.
