Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1039880, here are decompositions:

43 + 1039837 = 1039880
199 + 1039681 = 1039880
223 + 1039657 = 1039880
229 + 1039651 = 1039880
277 + 1039603 = 1039880
337 + 1039543 = 1039880
367 + 1039513 = 1039880
601 + 1039279 = 1039880

Showing the first eight; more decompositions exist.
