Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025978, here are decompositions:

61 + 1025917 = 1025978
67 + 1025911 = 1025978
139 + 1025839 = 1025978
211 + 1025767 = 1025978
229 + 1025749 = 1025978
271 + 1025707 = 1025978
337 + 1025641 = 1025978
367 + 1025611 = 1025978

Showing the first eight; more decompositions exist.
