Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042700, here are decompositions:

7 + 1042693 = 1042700
13 + 1042687 = 1042700
19 + 1042681 = 1042700
67 + 1042633 = 1042700
103 + 1042597 = 1042700
181 + 1042519 = 1042700
331 + 1042369 = 1042700
367 + 1042333 = 1042700

Showing the first eight; more decompositions exist.
