Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 994180, here are decompositions:

17 + 994163 = 994180
107 + 994073 = 994180
113 + 994067 = 994180
167 + 994013 = 994180
197 + 993983 = 994180
293 + 993887 = 994180
311 + 993869 = 994180
353 + 993827 = 994180

Showing the first eight; more decompositions exist.
