Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592864, here are decompositions:

31 + 31592833 = 31592864
67 + 31592797 = 31592864
103 + 31592761 = 31592864
181 + 31592683 = 31592864
223 + 31592641 = 31592864
307 + 31592557 = 31592864
313 + 31592551 = 31592864
397 + 31592467 = 31592864

Showing the first eight; more decompositions exist.
