Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 994178, here are decompositions:

37 + 994141 = 994178
109 + 994069 = 994178
127 + 994051 = 994178
139 + 994039 = 994178
151 + 994027 = 994178
181 + 993997 = 994178
271 + 993907 = 994178
337 + 993841 = 994178

Showing the first eight; more decompositions exist.
