Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592232, here are decompositions:

13 + 31592219 = 31592232
19 + 31592213 = 31592232
29 + 31592203 = 31592232
59 + 31592173 = 31592232
71 + 31592161 = 31592232
73 + 31592159 = 31592232
83 + 31592149 = 31592232
103 + 31592129 = 31592232

Showing the first eight; more decompositions exist.
