Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592798, here are decompositions:

19 + 31592779 = 31592798
37 + 31592761 = 31592798
157 + 31592641 = 31592798
199 + 31592599 = 31592798
241 + 31592557 = 31592798
331 + 31592467 = 31592798
409 + 31592389 = 31592798
421 + 31592377 = 31592798

Showing the first eight; more decompositions exist.
