Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31579332, here are decompositions:

11 + 31579321 = 31579332
41 + 31579291 = 31579332
131 + 31579201 = 31579332
139 + 31579193 = 31579332
151 + 31579181 = 31579332
193 + 31579139 = 31579332
199 + 31579133 = 31579332
223 + 31579109 = 31579332

Showing the first eight; more decompositions exist.
