Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592718, here are decompositions:

41 + 31592677 = 31592718
67 + 31592651 = 31592718
97 + 31592621 = 31592718
151 + 31592567 = 31592718
167 + 31592551 = 31592718
229 + 31592489 = 31592718
251 + 31592467 = 31592718
271 + 31592447 = 31592718

Showing the first eight; more decompositions exist.
