Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051218, here are decompositions:

37 + 1051181 = 1051218
41 + 1051177 = 1051218
61 + 1051157 = 1051218
67 + 1051151 = 1051218
71 + 1051147 = 1051218
79 + 1051139 = 1051218
137 + 1051081 = 1051218
139 + 1051079 = 1051218

Showing the first eight; more decompositions exist.
