Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1016578, here are decompositions:

5 + 1016573 = 1016578
11 + 1016567 = 1016578
89 + 1016489 = 1016578
137 + 1016441 = 1016578
179 + 1016399 = 1016578
239 + 1016339 = 1016578
347 + 1016231 = 1016578
419 + 1016159 = 1016578

Showing the first eight; more decompositions exist.
