Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015616, here are decompositions:

13 + 1015603 = 1015616
67 + 1015549 = 1015616
109 + 1015507 = 1015616
157 + 1015459 = 1015616
163 + 1015453 = 1015616
193 + 1015423 = 1015616
307 + 1015309 = 1015616
409 + 1015207 = 1015616

Showing the first eight; more decompositions exist.
