Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724284, here are decompositions:

31 + 8724253 = 8724284
43 + 8724241 = 8724284
61 + 8724223 = 8724284
103 + 8724181 = 8724284
157 + 8724127 = 8724284
211 + 8724073 = 8724284
271 + 8724013 = 8724284
307 + 8723977 = 8724284

Showing the first eight; more decompositions exist.
