Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724232, here are decompositions:

71 + 8724161 = 8724232
89 + 8724143 = 8724232
131 + 8724101 = 8724232
239 + 8723993 = 8724232
281 + 8723951 = 8724232
311 + 8723921 = 8724232
353 + 8723879 = 8724232
443 + 8723789 = 8724232

Showing the first eight; more decompositions exist.
