Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592316, here are decompositions:

5 + 31592311 = 31592316
59 + 31592257 = 31592316
97 + 31592219 = 31592316
103 + 31592213 = 31592316
113 + 31592203 = 31592316
157 + 31592159 = 31592316
167 + 31592149 = 31592316
193 + 31592123 = 31592316

Showing the first eight; more decompositions exist.
