Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8654140, here are decompositions:

17 + 8654123 = 8654140
23 + 8654117 = 8654140
29 + 8654111 = 8654140
41 + 8654099 = 8654140
83 + 8654057 = 8654140
101 + 8654039 = 8654140
107 + 8654033 = 8654140
113 + 8654027 = 8654140

Showing the first eight; more decompositions exist.
