Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 994688, here are decompositions:

31 + 994657 = 994688
67 + 994621 = 994688
109 + 994579 = 994688
127 + 994561 = 994688
139 + 994549 = 994688
199 + 994489 = 994688
241 + 994447 = 994688
271 + 994417 = 994688

Showing the first eight; more decompositions exist.
