Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051230, here are decompositions:

53 + 1051177 = 1051230
73 + 1051157 = 1051230
79 + 1051151 = 1051230
83 + 1051147 = 1051230
149 + 1051081 = 1051230
151 + 1051079 = 1051230
179 + 1051051 = 1051230
211 + 1051019 = 1051230

Showing the first eight; more decompositions exist.
