Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724148, here are decompositions:

5 + 8724143 = 8724148
47 + 8724101 = 8724148
197 + 8723951 = 8724148
227 + 8723921 = 8724148
239 + 8723909 = 8724148
269 + 8723879 = 8724148
359 + 8723789 = 8724148
509 + 8723639 = 8724148

Showing the first eight; more decompositions exist.
