Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1027580, here are decompositions:

13 + 1027567 = 1027580
31 + 1027549 = 1027580
61 + 1027519 = 1027580
97 + 1027483 = 1027580
109 + 1027471 = 1027580
163 + 1027417 = 1027580
223 + 1027357 = 1027580
373 + 1027207 = 1027580

Showing the first eight; more decompositions exist.
