Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559338, here are decompositions:

17 + 31559321 = 31559338
131 + 31559207 = 31559338
149 + 31559189 = 31559338
257 + 31559081 = 31559338
269 + 31559069 = 31559338
311 + 31559027 = 31559338
479 + 31558859 = 31559338
491 + 31558847 = 31559338

Showing the first eight; more decompositions exist.
