Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723544, here are decompositions:

13 + 8723531 = 8723544
23 + 8723521 = 8723544
47 + 8723497 = 8723544
61 + 8723483 = 8723544
103 + 8723441 = 8723544
107 + 8723437 = 8723544
157 + 8723387 = 8723544
191 + 8723353 = 8723544

Showing the first eight; more decompositions exist.
