Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449454, here are decompositions:

5 + 31449449 = 31449454
53 + 31449401 = 31449454
131 + 31449323 = 31449454
167 + 31449287 = 31449454
191 + 31449263 = 31449454
263 + 31449191 = 31449454
383 + 31449071 = 31449454
401 + 31449053 = 31449454

Showing the first eight; more decompositions exist.
