Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538448, here are decompositions:

37 + 538411 = 538448
139 + 538309 = 538448
151 + 538297 = 538448
181 + 538267 = 538448
199 + 538249 = 538448
331 + 538117 = 538448
397 + 538051 = 538448
457 + 537991 = 538448

Showing the first eight; more decompositions exist.
