Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1049680, here are decompositions:

3 + 1049677 = 1049680
17 + 1049663 = 1049680
41 + 1049639 = 1049680
131 + 1049549 = 1049680
197 + 1049483 = 1049680
251 + 1049429 = 1049680
293 + 1049387 = 1049680
347 + 1049333 = 1049680

Showing the first eight; more decompositions exist.
