Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015120, here are decompositions:

23 + 1015097 = 1015120
47 + 1015073 = 1015120
53 + 1015067 = 1015120
59 + 1015061 = 1015120
131 + 1014989 = 1015120
167 + 1014953 = 1015120
179 + 1014941 = 1015120
233 + 1014887 = 1015120

Showing the first eight; more decompositions exist.
