Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724106, here are decompositions:

5 + 8724101 = 8724106
113 + 8723993 = 8724106
173 + 8723933 = 8724106
197 + 8723909 = 8724106
227 + 8723879 = 8724106
317 + 8723789 = 8724106
467 + 8723639 = 8724106
647 + 8723459 = 8724106

Showing the first eight; more decompositions exist.
