Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989642, here are decompositions:

13 + 989629 = 989642
19 + 989623 = 989642
61 + 989581 = 989642
109 + 989533 = 989642
163 + 989479 = 989642
223 + 989419 = 989642
349 + 989293 = 989642
523 + 989119 = 989642

Showing the first eight; more decompositions exist.
