Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723534, here are decompositions:

3 + 8723531 = 8723534
13 + 8723521 = 8723534
37 + 8723497 = 8723534
97 + 8723437 = 8723534
181 + 8723353 = 8723534
223 + 8723311 = 8723534
331 + 8723203 = 8723534
397 + 8723137 = 8723534

Showing the first eight; more decompositions exist.
