Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592206, here are decompositions:

3 + 31592203 = 31592206
47 + 31592159 = 31592206
83 + 31592123 = 31592206
167 + 31592039 = 31592206
227 + 31591979 = 31592206
293 + 31591913 = 31592206
467 + 31591739 = 31592206
557 + 31591649 = 31592206

Showing the first eight; more decompositions exist.
