Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003238, here are decompositions:

37 + 1003201 = 1003238
97 + 1003141 = 1003238
127 + 1003111 = 1003238
151 + 1003087 = 1003238
199 + 1003039 = 1003238
307 + 1002931 = 1003238
367 + 1002871 = 1003238
421 + 1002817 = 1003238

Showing the first eight; more decompositions exist.
