Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051238, here are decompositions:

61 + 1051177 = 1051238
157 + 1051081 = 1051238
211 + 1051027 = 1051238
229 + 1051009 = 1051238
241 + 1050997 = 1051238
277 + 1050961 = 1051238
337 + 1050901 = 1051238
421 + 1050817 = 1051238

Showing the first eight; more decompositions exist.
