Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723184, here are decompositions:

47 + 8723137 = 8723184
61 + 8723123 = 8723184
103 + 8723081 = 8723184
131 + 8723053 = 8723184
137 + 8723047 = 8723184
167 + 8723017 = 8723184
191 + 8722993 = 8723184
193 + 8722991 = 8723184

Showing the first eight; more decompositions exist.
