Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015226, here are decompositions:

19 + 1015207 = 1015226
67 + 1015159 = 1015226
103 + 1015123 = 1015226
337 + 1014889 = 1015226
349 + 1014877 = 1015226
409 + 1014817 = 1015226
439 + 1014787 = 1015226
463 + 1014763 = 1015226

Showing the first eight; more decompositions exist.
