Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015168, here are decompositions:

5 + 1015163 = 1015168
29 + 1015139 = 1015168
41 + 1015127 = 1015168
71 + 1015097 = 1015168
101 + 1015067 = 1015168
107 + 1015061 = 1015168
179 + 1014989 = 1015168
227 + 1014941 = 1015168

Showing the first eight; more decompositions exist.
