Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724274, here are decompositions:

5 + 8724269 = 8724274
11 + 8724263 = 8724274
113 + 8724161 = 8724274
131 + 8724143 = 8724274
173 + 8724101 = 8724274
281 + 8723993 = 8724274
353 + 8723921 = 8724274
467 + 8723807 = 8724274

Showing the first eight; more decompositions exist.
