Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015288, here are decompositions:

11 + 1015277 = 1015288
89 + 1015199 = 1015288
149 + 1015139 = 1015288
191 + 1015097 = 1015288
227 + 1015061 = 1015288
347 + 1014941 = 1015288
401 + 1014887 = 1015288
419 + 1014869 = 1015288

Showing the first eight; more decompositions exist.
