Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592586, here are decompositions:

19 + 31592567 = 31592586
29 + 31592557 = 31592586
97 + 31592489 = 31592586
139 + 31592447 = 31592586
149 + 31592437 = 31592586
163 + 31592423 = 31592586
197 + 31592389 = 31592586
229 + 31592357 = 31592586

Showing the first eight; more decompositions exist.
