Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592262, here are decompositions:

5 + 31592257 = 31592262
43 + 31592219 = 31592262
59 + 31592203 = 31592262
89 + 31592173 = 31592262
101 + 31592161 = 31592262
103 + 31592159 = 31592262
113 + 31592149 = 31592262
139 + 31592123 = 31592262

Showing the first eight; more decompositions exist.
