Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012238, here are decompositions:

37 + 1012201 = 1012238
67 + 1012171 = 1012238
79 + 1012159 = 1012238
151 + 1012087 = 1012238
229 + 1012009 = 1012238
277 + 1011961 = 1012238
349 + 1011889 = 1012238
421 + 1011817 = 1012238

Showing the first eight; more decompositions exist.
