Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724132, here are decompositions:

5 + 8724127 = 8724132
31 + 8724101 = 8724132
59 + 8724073 = 8724132
61 + 8724071 = 8724132
139 + 8723993 = 8724132
181 + 8723951 = 8724132
199 + 8723933 = 8724132
211 + 8723921 = 8724132

Showing the first eight; more decompositions exist.
