Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1039988, here are decompositions:

67 + 1039921 = 1039988
97 + 1039891 = 1039988
151 + 1039837 = 1039988
199 + 1039789 = 1039988
307 + 1039681 = 1039988
331 + 1039657 = 1039988
337 + 1039651 = 1039988
601 + 1039387 = 1039988

Showing the first eight; more decompositions exist.
