Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986442, here are decompositions:

5 + 986437 = 986442
13 + 986429 = 986442
31 + 986411 = 986442
73 + 986369 = 986442
103 + 986339 = 986442
109 + 986333 = 986442
229 + 986213 = 986442
251 + 986191 = 986442

Showing the first eight; more decompositions exist.
