Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724118, here are decompositions:

17 + 8724101 = 8724118
47 + 8724071 = 8724118
131 + 8723987 = 8724118
167 + 8723951 = 8724118
197 + 8723921 = 8724118
239 + 8723879 = 8724118
311 + 8723807 = 8724118
479 + 8723639 = 8724118

Showing the first eight; more decompositions exist.
