Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724150, here are decompositions:

7 + 8724143 = 8724150
11 + 8724139 = 8724150
23 + 8724127 = 8724150
79 + 8724071 = 8724150
137 + 8724013 = 8724150
157 + 8723993 = 8724150
163 + 8723987 = 8724150
173 + 8723977 = 8724150

Showing the first eight; more decompositions exist.
