Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019126, here are decompositions:

7 + 1019119 = 1019126
67 + 1019059 = 1019126
103 + 1019023 = 1019126
127 + 1018999 = 1019126
139 + 1018987 = 1019126
223 + 1018903 = 1019126
313 + 1018813 = 1019126
337 + 1018789 = 1019126

Showing the first eight; more decompositions exist.
