Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592822, here are decompositions:

13 + 31592809 = 31592822
43 + 31592779 = 31592822
61 + 31592761 = 31592822
139 + 31592683 = 31592822
181 + 31592641 = 31592822
223 + 31592599 = 31592822
271 + 31592551 = 31592822
433 + 31592389 = 31592822

Showing the first eight; more decompositions exist.
