Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8610240, here are decompositions:

11 + 8610229 = 8610240
13 + 8610227 = 8610240
31 + 8610209 = 8610240
43 + 8610197 = 8610240
71 + 8610169 = 8610240
73 + 8610167 = 8610240
101 + 8610139 = 8610240
103 + 8610137 = 8610240

Showing the first eight; more decompositions exist.
