Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592916, here are decompositions:

67 + 31592849 = 31592916
73 + 31592843 = 31592916
83 + 31592833 = 31592916
107 + 31592809 = 31592916
137 + 31592779 = 31592916
233 + 31592683 = 31592916
239 + 31592677 = 31592916
317 + 31592599 = 31592916

Showing the first eight; more decompositions exist.
