Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559350, here are decompositions:

29 + 31559321 = 31559350
131 + 31559219 = 31559350
257 + 31559093 = 31559350
269 + 31559081 = 31559350
281 + 31559069 = 31559350
353 + 31558997 = 31559350
467 + 31558883 = 31559350
491 + 31558859 = 31559350

Showing the first eight; more decompositions exist.
