Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592512, here are decompositions:

23 + 31592489 = 31592512
59 + 31592453 = 31592512
89 + 31592423 = 31592512
101 + 31592411 = 31592512
293 + 31592219 = 31592512
353 + 31592159 = 31592512
383 + 31592129 = 31592512
389 + 31592123 = 31592512

Showing the first eight; more decompositions exist.
