Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724222, here are decompositions:

41 + 8724181 = 8724222
53 + 8724169 = 8724222
61 + 8724161 = 8724222
79 + 8724143 = 8724222
83 + 8724139 = 8724222
149 + 8724073 = 8724222
151 + 8724071 = 8724222
229 + 8723993 = 8724222

Showing the first eight; more decompositions exist.
