Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724124, here are decompositions:

23 + 8724101 = 8724124
53 + 8724071 = 8724124
131 + 8723993 = 8724124
137 + 8723987 = 8724124
173 + 8723951 = 8724124
191 + 8723933 = 8724124
317 + 8723807 = 8724124
593 + 8723531 = 8724124

Showing the first eight; more decompositions exist.
