Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1048580, here are decompositions:

7 + 1048573 = 1048580
31 + 1048549 = 1048580
73 + 1048507 = 1048580
157 + 1048423 = 1048580
193 + 1048387 = 1048580
223 + 1048357 = 1048580
271 + 1048309 = 1048580
307 + 1048273 = 1048580

Showing the first eight; more decompositions exist.
