Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1006646, here are decompositions:

13 + 1006633 = 1006646
37 + 1006609 = 1006646
103 + 1006543 = 1006646
139 + 1006507 = 1006646
307 + 1006339 = 1006646
313 + 1006333 = 1006646
337 + 1006309 = 1006646
367 + 1006279 = 1006646

Showing the first eight; more decompositions exist.
