Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042844, here are decompositions:

7 + 1042837 = 1042844
151 + 1042693 = 1042844
157 + 1042687 = 1042844
163 + 1042681 = 1042844
211 + 1042633 = 1042844
463 + 1042381 = 1042844
487 + 1042357 = 1042844
571 + 1042273 = 1042844

Showing the first eight; more decompositions exist.
