Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592764, here are decompositions:

3 + 31592761 = 31592764
17 + 31592747 = 31592764
101 + 31592663 = 31592764
113 + 31592651 = 31592764
197 + 31592567 = 31592764
233 + 31592531 = 31592764
311 + 31592453 = 31592764
317 + 31592447 = 31592764

Showing the first eight; more decompositions exist.
