Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592266, here are decompositions:

47 + 31592219 = 31592266
53 + 31592213 = 31592266
107 + 31592159 = 31592266
137 + 31592129 = 31592266
227 + 31592039 = 31592266
269 + 31591997 = 31592266
353 + 31591913 = 31592266
599 + 31591667 = 31592266

Showing the first eight; more decompositions exist.
