Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592992, here are decompositions:

71 + 31592921 = 31592992
149 + 31592843 = 31592992
461 + 31592531 = 31592992
503 + 31592489 = 31592992
569 + 31592423 = 31592992
701 + 31592291 = 31592992
773 + 31592219 = 31592992
863 + 31592129 = 31592992

Showing the first eight; more decompositions exist.
