Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8654142, here are decompositions:

19 + 8654123 = 8654142
31 + 8654111 = 8654142
43 + 8654099 = 8654142
53 + 8654089 = 8654142
103 + 8654039 = 8654142
109 + 8654033 = 8654142
113 + 8654029 = 8654142
131 + 8654011 = 8654142

Showing the first eight; more decompositions exist.
