Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019438, here are decompositions:

61 + 1019377 = 1019438
109 + 1019329 = 1019438
157 + 1019281 = 1019438
181 + 1019257 = 1019438
229 + 1019209 = 1019438
241 + 1019197 = 1019438
367 + 1019071 = 1019438
379 + 1019059 = 1019438

Showing the first eight; more decompositions exist.
