Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592792, here are decompositions:

13 + 31592779 = 31592792
19 + 31592773 = 31592792
31 + 31592761 = 31592792
109 + 31592683 = 31592792
151 + 31592641 = 31592792
193 + 31592599 = 31592792
241 + 31592551 = 31592792
619 + 31592173 = 31592792

Showing the first eight; more decompositions exist.
