Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042580, here are decompositions:

3 + 1042577 = 1042580
61 + 1042519 = 1042580
181 + 1042399 = 1042580
199 + 1042381 = 1042580
211 + 1042369 = 1042580
223 + 1042357 = 1042580
271 + 1042309 = 1042580
307 + 1042273 = 1042580

Showing the first eight; more decompositions exist.
