Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015580, here are decompositions:

19 + 1015561 = 1015580
31 + 1015549 = 1015580
73 + 1015507 = 1015580
79 + 1015501 = 1015580
109 + 1015471 = 1015580
127 + 1015453 = 1015580
157 + 1015423 = 1015580
211 + 1015369 = 1015580

Showing the first eight; more decompositions exist.
