Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712004, here are decompositions:

17 + 8711987 = 8712004
53 + 8711951 = 8712004
71 + 8711933 = 8712004
83 + 8711921 = 8712004
107 + 8711897 = 8712004
137 + 8711867 = 8712004
227 + 8711777 = 8712004
263 + 8711741 = 8712004

Showing the first eight; more decompositions exist.
