Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559362, here are decompositions:

11 + 31559351 = 31559362
41 + 31559321 = 31559362
173 + 31559189 = 31559362
269 + 31559093 = 31559362
281 + 31559081 = 31559362
293 + 31559069 = 31559362
311 + 31559051 = 31559362
389 + 31558973 = 31559362

Showing the first eight; more decompositions exist.
