Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999142, here are decompositions:

41 + 999101 = 999142
59 + 999083 = 999142
113 + 999029 = 999142
173 + 998969 = 999142
191 + 998951 = 999142
233 + 998909 = 999142
281 + 998861 = 999142
311 + 998831 = 999142

Showing the first eight; more decompositions exist.
