Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670028, here are decompositions:

47 + 8669981 = 8670028
89 + 8669939 = 8670028
131 + 8669897 = 8670028
149 + 8669879 = 8670028
167 + 8669861 = 8670028
197 + 8669831 = 8670028
251 + 8669777 = 8670028
359 + 8669669 = 8670028

Showing the first eight; more decompositions exist.
