Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449514, here are decompositions:

113 + 31449401 = 31449514
137 + 31449377 = 31449514
191 + 31449323 = 31449514
227 + 31449287 = 31449514
251 + 31449263 = 31449514
281 + 31449233 = 31449514
431 + 31449083 = 31449514
443 + 31449071 = 31449514

Showing the first eight; more decompositions exist.
