Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986508, here are decompositions:

11 + 986497 = 986508
31 + 986477 = 986508
37 + 986471 = 986508
71 + 986437 = 986508
79 + 986429 = 986508
97 + 986411 = 986508
139 + 986369 = 986508
157 + 986351 = 986508

Showing the first eight; more decompositions exist.
