Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045166, here are decompositions:

13 + 1045153 = 1045166
37 + 1045129 = 1045166
43 + 1045123 = 1045166
103 + 1045063 = 1045166
139 + 1045027 = 1045166
163 + 1045003 = 1045166
277 + 1044889 = 1045166
307 + 1044859 = 1045166

Showing the first eight; more decompositions exist.
