Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042730, here are decompositions:

37 + 1042693 = 1042730
43 + 1042687 = 1042730
97 + 1042633 = 1042730
211 + 1042519 = 1042730
331 + 1042399 = 1042730
349 + 1042381 = 1042730
373 + 1042357 = 1042730
397 + 1042333 = 1042730

Showing the first eight; more decompositions exist.
