Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592734, here are decompositions:

71 + 31592663 = 31592734
83 + 31592651 = 31592734
113 + 31592621 = 31592734
167 + 31592567 = 31592734
281 + 31592453 = 31592734
311 + 31592423 = 31592734
317 + 31592417 = 31592734
443 + 31592291 = 31592734

Showing the first eight; more decompositions exist.
