Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31621414, here are decompositions:

47 + 31621367 = 31621414
197 + 31621217 = 31621414
257 + 31621157 = 31621414
263 + 31621151 = 31621414
281 + 31621133 = 31621414
317 + 31621097 = 31621414
401 + 31621013 = 31621414
467 + 31620947 = 31621414

Showing the first eight; more decompositions exist.
