Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724170, here are decompositions:

31 + 8724139 = 8724170
43 + 8724127 = 8724170
97 + 8724073 = 8724170
157 + 8724013 = 8724170
193 + 8723977 = 8724170
223 + 8723947 = 8724170
241 + 8723929 = 8724170
271 + 8723899 = 8724170

Showing the first eight; more decompositions exist.
