Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986430, here are decompositions:

13 + 986417 = 986430
19 + 986411 = 986430
61 + 986369 = 986430
79 + 986351 = 986430
97 + 986333 = 986430
149 + 986281 = 986430
163 + 986267 = 986430
173 + 986257 = 986430

Showing the first eight; more decompositions exist.
