Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724804, here are decompositions:

5 + 8724799 = 8724804
17 + 8724787 = 8724804
83 + 8724721 = 8724804
107 + 8724697 = 8724804
163 + 8724641 = 8724804
173 + 8724631 = 8724804
293 + 8724511 = 8724804
307 + 8724497 = 8724804

Showing the first eight; more decompositions exist.
