Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724244, here are decompositions:

3 + 8724241 = 8724244
83 + 8724161 = 8724244
101 + 8724143 = 8724244
173 + 8724071 = 8724244
251 + 8723993 = 8724244
257 + 8723987 = 8724244
293 + 8723951 = 8724244
311 + 8723933 = 8724244

Showing the first eight; more decompositions exist.
