Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592952, here are decompositions:

5 + 31592947 = 31592952
29 + 31592923 = 31592952
31 + 31592921 = 31592952
103 + 31592849 = 31592952
109 + 31592843 = 31592952
173 + 31592779 = 31592952
179 + 31592773 = 31592952
191 + 31592761 = 31592952

Showing the first eight; more decompositions exist.
