Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1027380, here are decompositions:

23 + 1027357 = 1027380
59 + 1027321 = 1027380
61 + 1027319 = 1027380
103 + 1027277 = 1027380
139 + 1027241 = 1027380
157 + 1027223 = 1027380
173 + 1027207 = 1027380
181 + 1027199 = 1027380

Showing the first eight; more decompositions exist.
