Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592620, here are decompositions:

53 + 31592567 = 31592620
89 + 31592531 = 31592620
131 + 31592489 = 31592620
167 + 31592453 = 31592620
173 + 31592447 = 31592620
197 + 31592423 = 31592620
251 + 31592369 = 31592620
263 + 31592357 = 31592620

Showing the first eight; more decompositions exist.
