Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724262, here are decompositions:

3 + 8724259 = 8724262
101 + 8724161 = 8724262
191 + 8724071 = 8724262
269 + 8723993 = 8724262
311 + 8723951 = 8724262
353 + 8723909 = 8724262
359 + 8723903 = 8724262
383 + 8723879 = 8724262

Showing the first eight; more decompositions exist.
