Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728004, here are decompositions:

67 + 8727937 = 8728004
73 + 8727931 = 8728004
97 + 8727907 = 8728004
277 + 8727727 = 8728004
331 + 8727673 = 8728004
421 + 8727583 = 8728004
577 + 8727427 = 8728004
661 + 8727343 = 8728004

Showing the first eight; more decompositions exist.
