Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592506, here are decompositions:

17 + 31592489 = 31592506
53 + 31592453 = 31592506
59 + 31592447 = 31592506
83 + 31592423 = 31592506
89 + 31592417 = 31592506
137 + 31592369 = 31592506
149 + 31592357 = 31592506
293 + 31592213 = 31592506

Showing the first eight; more decompositions exist.
