Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1027978, here are decompositions:

47 + 1027931 = 1027978
137 + 1027841 = 1027978
179 + 1027799 = 1027978
191 + 1027787 = 1027978
227 + 1027751 = 1027978
239 + 1027739 = 1027978
251 + 1027727 = 1027978
431 + 1027547 = 1027978

Showing the first eight; more decompositions exist.
