Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015448, here are decompositions:

79 + 1015369 = 1015448
139 + 1015309 = 1015448
241 + 1015207 = 1015448
277 + 1015171 = 1015448
367 + 1015081 = 1015448
397 + 1015051 = 1015448
409 + 1015039 = 1015448
439 + 1015009 = 1015448

Showing the first eight; more decompositions exist.
