Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009988, here are decompositions:

37 + 1009951 = 1009988
61 + 1009927 = 1009988
79 + 1009909 = 1009988
151 + 1009837 = 1009988
181 + 1009807 = 1009988
241 + 1009747 = 1009988
337 + 1009651 = 1009988
367 + 1009621 = 1009988

Showing the first eight; more decompositions exist.
