Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724158, here are decompositions:

19 + 8724139 = 8724158
31 + 8724127 = 8724158
181 + 8723977 = 8724158
211 + 8723947 = 8724158
229 + 8723929 = 8724158
271 + 8723887 = 8724158
307 + 8723851 = 8724158
337 + 8723821 = 8724158

Showing the first eight; more decompositions exist.
