Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8735240, here are decompositions:

43 + 8735197 = 8735240
61 + 8735179 = 8735240
103 + 8735137 = 8735240
127 + 8735113 = 8735240
193 + 8735047 = 8735240
211 + 8735029 = 8735240
229 + 8735011 = 8735240
421 + 8734819 = 8735240

Showing the first eight; more decompositions exist.
