Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724090, here are decompositions:

17 + 8724073 = 8724090
19 + 8724071 = 8724090
97 + 8723993 = 8724090
103 + 8723987 = 8724090
113 + 8723977 = 8724090
139 + 8723951 = 8724090
157 + 8723933 = 8724090
181 + 8723909 = 8724090

Showing the first eight; more decompositions exist.
