Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719140, here are decompositions:

7 + 8719133 = 8719140
13 + 8719127 = 8719140
41 + 8719099 = 8719140
83 + 8719057 = 8719140
103 + 8719037 = 8719140
109 + 8719031 = 8719140
137 + 8719003 = 8719140
167 + 8718973 = 8719140

Showing the first eight; more decompositions exist.
