Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 994142, here are decompositions:

73 + 994069 = 994142
103 + 994039 = 994142
181 + 993961 = 994142
199 + 993943 = 994142
223 + 993919 = 994142
229 + 993913 = 994142
349 + 993793 = 994142
379 + 993763 = 994142

Showing the first eight; more decompositions exist.
