Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538454, here are decompositions:

31 + 538423 = 538454
43 + 538411 = 538454
97 + 538357 = 538454
151 + 538303 = 538454
157 + 538297 = 538454
307 + 538147 = 538454
331 + 538123 = 538454
337 + 538117 = 538454

Showing the first eight; more decompositions exist.
