Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592722, here are decompositions:

59 + 31592663 = 31592722
71 + 31592651 = 31592722
101 + 31592621 = 31592722
191 + 31592531 = 31592722
233 + 31592489 = 31592722
269 + 31592453 = 31592722
311 + 31592411 = 31592722
353 + 31592369 = 31592722

Showing the first eight; more decompositions exist.
