Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042646, here are decompositions:

13 + 1042633 = 1042646
37 + 1042609 = 1042646
127 + 1042519 = 1042646
277 + 1042369 = 1042646
313 + 1042333 = 1042646
337 + 1042309 = 1042646
373 + 1042273 = 1042646
379 + 1042267 = 1042646

Showing the first eight; more decompositions exist.
