Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986558, here are decompositions:

61 + 986497 = 986558
271 + 986287 = 986558
277 + 986281 = 986558
367 + 986191 = 986558
409 + 986149 = 986558
421 + 986137 = 986558
457 + 986101 = 986558
487 + 986071 = 986558

Showing the first eight; more decompositions exist.
