Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724250, here are decompositions:

89 + 8724161 = 8724250
107 + 8724143 = 8724250
149 + 8724101 = 8724250
179 + 8724071 = 8724250
257 + 8723993 = 8724250
263 + 8723987 = 8724250
317 + 8723933 = 8724250
347 + 8723903 = 8724250

Showing the first eight; more decompositions exist.
