Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015252, here are decompositions:

53 + 1015199 = 1015252
89 + 1015163 = 1015252
113 + 1015139 = 1015252
179 + 1015073 = 1015252
191 + 1015061 = 1015252
263 + 1014989 = 1015252
311 + 1014941 = 1015252
383 + 1014869 = 1015252

Showing the first eight; more decompositions exist.
