Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592928, here are decompositions:

5 + 31592923 = 31592928
7 + 31592921 = 31592928
79 + 31592849 = 31592928
131 + 31592797 = 31592928
149 + 31592779 = 31592928
167 + 31592761 = 31592928
181 + 31592747 = 31592928
251 + 31592677 = 31592928

Showing the first eight; more decompositions exist.
