Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009238, here are decompositions:

31 + 1009207 = 1009238
37 + 1009201 = 1009238
79 + 1009159 = 1009238
337 + 1008901 = 1009238
367 + 1008871 = 1009238
379 + 1008859 = 1009238
409 + 1008829 = 1009238
421 + 1008817 = 1009238

Showing the first eight; more decompositions exist.
