Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724086, here are decompositions:

13 + 8724073 = 8724086
73 + 8724013 = 8724086
109 + 8723977 = 8724086
139 + 8723947 = 8724086
157 + 8723929 = 8724086
193 + 8723893 = 8724086
199 + 8723887 = 8724086
379 + 8723707 = 8724086

Showing the first eight; more decompositions exist.
