Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989516, here are decompositions:

37 + 989479 = 989516
97 + 989419 = 989516
139 + 989377 = 989516
163 + 989353 = 989516
193 + 989323 = 989516
223 + 989293 = 989516
277 + 989239 = 989516
397 + 989119 = 989516

Showing the first eight; more decompositions exist.
