Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015140, here are decompositions:

13 + 1015127 = 1015140
17 + 1015123 = 1015140
43 + 1015097 = 1015140
47 + 1015093 = 1015140
59 + 1015081 = 1015140
67 + 1015073 = 1015140
73 + 1015067 = 1015140
79 + 1015061 = 1015140

Showing the first eight; more decompositions exist.
