Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722004, here are decompositions:

3 + 8722001 = 8722004
7 + 8721997 = 8722004
97 + 8721907 = 8722004
127 + 8721877 = 8722004
241 + 8721763 = 8722004
331 + 8721673 = 8722004
337 + 8721667 = 8722004
373 + 8721631 = 8722004

Showing the first eight; more decompositions exist.
