Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 982538, here are decompositions:

157 + 982381 = 982538
199 + 982339 = 982538
307 + 982231 = 982538
367 + 982171 = 982538
421 + 982117 = 982538
439 + 982099 = 982538
577 + 981961 = 982538
619 + 981919 = 982538

Showing the first eight; more decompositions exist.
