Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1038458, here are decompositions:

37 + 1038421 = 1038458
67 + 1038391 = 1038458
139 + 1038319 = 1038458
151 + 1038307 = 1038458
199 + 1038259 = 1038458
271 + 1038187 = 1038458
331 + 1038127 = 1038458
439 + 1038019 = 1038458

Showing the first eight; more decompositions exist.
