Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592758, here are decompositions:

11 + 31592747 = 31592758
107 + 31592651 = 31592758
137 + 31592621 = 31592758
191 + 31592567 = 31592758
227 + 31592531 = 31592758
269 + 31592489 = 31592758
311 + 31592447 = 31592758
347 + 31592411 = 31592758

Showing the first eight; more decompositions exist.
