Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592302, here are decompositions:

11 + 31592291 = 31592302
83 + 31592219 = 31592302
89 + 31592213 = 31592302
173 + 31592129 = 31592302
179 + 31592123 = 31592302
251 + 31592051 = 31592302
263 + 31592039 = 31592302
389 + 31591913 = 31592302

Showing the first eight; more decompositions exist.
