Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592536, here are decompositions:

5 + 31592531 = 31592536
47 + 31592489 = 31592536
83 + 31592453 = 31592536
89 + 31592447 = 31592536
113 + 31592423 = 31592536
167 + 31592369 = 31592536
179 + 31592357 = 31592536
317 + 31592219 = 31592536

Showing the first eight; more decompositions exist.
