Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1027478, here are decompositions:

7 + 1027471 = 1027478
19 + 1027459 = 1027478
61 + 1027417 = 1027478
157 + 1027321 = 1027478
271 + 1027207 = 1027478
349 + 1027129 = 1027478
499 + 1026979 = 1027478
619 + 1026859 = 1027478

Showing the first eight; more decompositions exist.
