Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989618, here are decompositions:

37 + 989581 = 989618
61 + 989557 = 989618
139 + 989479 = 989618
151 + 989467 = 989618
199 + 989419 = 989618
241 + 989377 = 989618
271 + 989347 = 989618
277 + 989341 = 989618

Showing the first eight; more decompositions exist.
