Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670078, here are decompositions:

7 + 8670071 = 8670078
37 + 8670041 = 8670078
41 + 8670037 = 8670078
47 + 8670031 = 8670078
71 + 8670007 = 8670078
89 + 8669989 = 8670078
97 + 8669981 = 8670078
139 + 8669939 = 8670078

Showing the first eight; more decompositions exist.
