Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592858, here are decompositions:

61 + 31592797 = 31592858
79 + 31592779 = 31592858
97 + 31592761 = 31592858
181 + 31592677 = 31592858
307 + 31592551 = 31592858
421 + 31592437 = 31592858
547 + 31592311 = 31592858
601 + 31592257 = 31592858

Showing the first eight; more decompositions exist.
