Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015622, here are decompositions:

19 + 1015603 = 1015622
61 + 1015561 = 1015622
73 + 1015549 = 1015622
151 + 1015471 = 1015622
163 + 1015459 = 1015622
199 + 1015423 = 1015622
313 + 1015309 = 1015622
463 + 1015159 = 1015622

Showing the first eight; more decompositions exist.
