Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492552, here are decompositions:

11 + 31492541 = 31492552
23 + 31492529 = 31492552
59 + 31492493 = 31492552
131 + 31492421 = 31492552
149 + 31492403 = 31492552
233 + 31492319 = 31492552
293 + 31492259 = 31492552
389 + 31492163 = 31492552

Showing the first eight; more decompositions exist.
