Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 994578, here are decompositions:

7 + 994571 = 994578
17 + 994561 = 994578
19 + 994559 = 994578
29 + 994549 = 994578
89 + 994489 = 994578
107 + 994471 = 994578
131 + 994447 = 994578
239 + 994339 = 994578

Showing the first eight; more decompositions exist.
