Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019154, here are decompositions:

61 + 1019093 = 1019154
83 + 1019071 = 1019154
131 + 1019023 = 1019154
167 + 1018987 = 1019154
173 + 1018981 = 1019154
197 + 1018957 = 1019154
223 + 1018931 = 1019154
251 + 1018903 = 1019154

Showing the first eight; more decompositions exist.
