Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538466, here are decompositions:

17 + 31538449 = 31538466
23 + 31538443 = 31538466
59 + 31538407 = 31538466
137 + 31538329 = 31538466
139 + 31538327 = 31538466
227 + 31538239 = 31538466
263 + 31538203 = 31538466
313 + 31538153 = 31538466

Showing the first eight; more decompositions exist.
