Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047686, here are decompositions:

19 + 1047667 = 1047686
37 + 1047649 = 1047686
97 + 1047589 = 1047686
127 + 1047559 = 1047686
307 + 1047379 = 1047686
313 + 1047373 = 1047686
373 + 1047313 = 1047686
379 + 1047307 = 1047686

Showing the first eight; more decompositions exist.
