Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042218, here are decompositions:

7 + 1042211 = 1042218
31 + 1042187 = 1042218
97 + 1042121 = 1042218
109 + 1042109 = 1042218
127 + 1042091 = 1042218
131 + 1042087 = 1042218
137 + 1042081 = 1042218
179 + 1042039 = 1042218

Showing the first eight; more decompositions exist.
