Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1004720, here are decompositions:

43 + 1004677 = 1004720
61 + 1004659 = 1004720
193 + 1004527 = 1004720
271 + 1004449 = 1004720
349 + 1004371 = 1004720
397 + 1004323 = 1004720
433 + 1004287 = 1004720
487 + 1004233 = 1004720

Showing the first eight; more decompositions exist.
