Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015648, here are decompositions:

47 + 1015601 = 1015648
89 + 1015559 = 1015648
107 + 1015541 = 1015648
131 + 1015517 = 1015648
149 + 1015499 = 1015648
167 + 1015481 = 1015648
197 + 1015451 = 1015648
239 + 1015409 = 1015648

Showing the first eight; more decompositions exist.
