Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592748, here are decompositions:

71 + 31592677 = 31592748
97 + 31592651 = 31592748
107 + 31592641 = 31592748
127 + 31592621 = 31592748
149 + 31592599 = 31592748
181 + 31592567 = 31592748
191 + 31592557 = 31592748
197 + 31592551 = 31592748

Showing the first eight; more decompositions exist.
