Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538278, here are decompositions:

11 + 538267 = 538278
19 + 538259 = 538278
29 + 538249 = 538278
31 + 538247 = 538278
79 + 538199 = 538278
127 + 538151 = 538278
131 + 538147 = 538278
151 + 538127 = 538278

Showing the first eight; more decompositions exist.
