Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592946, here are decompositions:

23 + 31592923 = 31592946
97 + 31592849 = 31592946
103 + 31592843 = 31592946
113 + 31592833 = 31592946
137 + 31592809 = 31592946
149 + 31592797 = 31592946
167 + 31592779 = 31592946
173 + 31592773 = 31592946

Showing the first eight; more decompositions exist.
