Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592196, here are decompositions:

23 + 31592173 = 31592196
37 + 31592159 = 31592196
47 + 31592149 = 31592196
67 + 31592129 = 31592196
73 + 31592123 = 31592196
149 + 31592047 = 31592196
157 + 31592039 = 31592196
197 + 31591999 = 31592196

Showing the first eight; more decompositions exist.
