Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019172, here are decompositions:

43 + 1019129 = 1019172
53 + 1019119 = 1019172
79 + 1019093 = 1019172
101 + 1019071 = 1019172
103 + 1019069 = 1019172
113 + 1019059 = 1019172
139 + 1019033 = 1019172
149 + 1019023 = 1019172

Showing the first eight; more decompositions exist.
