Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019618, here are decompositions:

109 + 1019509 = 1019618
139 + 1019479 = 1019618
151 + 1019467 = 1019618
241 + 1019377 = 1019618
337 + 1019281 = 1019618
367 + 1019251 = 1019618
409 + 1019209 = 1019618
421 + 1019197 = 1019618

Showing the first eight; more decompositions exist.
