Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986492, here are decompositions:

211 + 986281 = 986492
349 + 986143 = 986492
379 + 986113 = 986492
421 + 986071 = 986492
439 + 986053 = 986492
499 + 985993 = 986492
523 + 985969 = 986492
541 + 985951 = 986492

Showing the first eight; more decompositions exist.
