Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8706140, here are decompositions:

61 + 8706079 = 8706140
67 + 8706073 = 8706140
127 + 8706013 = 8706140
139 + 8706001 = 8706140
181 + 8705959 = 8706140
199 + 8705941 = 8706140
229 + 8705911 = 8706140
337 + 8705803 = 8706140

Showing the first eight; more decompositions exist.
