Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592550, here are decompositions:

19 + 31592531 = 31592550
61 + 31592489 = 31592550
83 + 31592467 = 31592550
97 + 31592453 = 31592550
103 + 31592447 = 31592550
113 + 31592437 = 31592550
127 + 31592423 = 31592550
139 + 31592411 = 31592550

Showing the first eight; more decompositions exist.
