Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989636, here are decompositions:

7 + 989629 = 989636
13 + 989623 = 989636
79 + 989557 = 989636
103 + 989533 = 989636
157 + 989479 = 989636
283 + 989353 = 989636
313 + 989323 = 989636
397 + 989239 = 989636

Showing the first eight; more decompositions exist.
