Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000580, here are decompositions:

3 + 1000577 = 1000580
43 + 1000537 = 1000580
73 + 1000507 = 1000580
127 + 1000453 = 1000580
151 + 1000429 = 1000580
157 + 1000423 = 1000580
199 + 1000381 = 1000580
223 + 1000357 = 1000580

Showing the first eight; more decompositions exist.
