Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047806, here are decompositions:

43 + 1047763 = 1047806
103 + 1047703 = 1047806
139 + 1047667 = 1047806
157 + 1047649 = 1047806
307 + 1047499 = 1047806
337 + 1047469 = 1047806
433 + 1047373 = 1047806
439 + 1047367 = 1047806

Showing the first eight; more decompositions exist.
