Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592618, here are decompositions:

19 + 31592599 = 31592618
61 + 31592557 = 31592618
67 + 31592551 = 31592618
151 + 31592467 = 31592618
181 + 31592437 = 31592618
229 + 31592389 = 31592618
241 + 31592377 = 31592618
271 + 31592347 = 31592618

Showing the first eight; more decompositions exist.
