Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015556, here are decompositions:

7 + 1015549 = 1015556
97 + 1015459 = 1015556
103 + 1015453 = 1015556
193 + 1015363 = 1015556
349 + 1015207 = 1015556
397 + 1015159 = 1015556
433 + 1015123 = 1015556
463 + 1015093 = 1015556

Showing the first eight; more decompositions exist.
