Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019178, here are decompositions:

5 + 1019173 = 1019178
59 + 1019119 = 1019178
101 + 1019077 = 1019178
107 + 1019071 = 1019178
109 + 1019069 = 1019178
179 + 1018999 = 1019178
191 + 1018987 = 1019178
197 + 1018981 = 1019178

Showing the first eight; more decompositions exist.
