Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559482, here are decompositions:

11 + 31559471 = 31559482
131 + 31559351 = 31559482
263 + 31559219 = 31559482
293 + 31559189 = 31559482
389 + 31559093 = 31559482
401 + 31559081 = 31559482
431 + 31559051 = 31559482
509 + 31558973 = 31559482

Showing the first eight; more decompositions exist.
