Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019148, here are decompositions:

19 + 1019129 = 1019148
29 + 1019119 = 1019148
71 + 1019077 = 1019148
79 + 1019069 = 1019148
89 + 1019059 = 1019148
149 + 1018999 = 1019148
167 + 1018981 = 1019148
181 + 1018967 = 1019148

Showing the first eight; more decompositions exist.
