Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738964, here are decompositions:

7 + 8738957 = 8738964
83 + 8738881 = 8738964
127 + 8738837 = 8738964
151 + 8738813 = 8738964
163 + 8738801 = 8738964
181 + 8738783 = 8738964
197 + 8738767 = 8738964
251 + 8738713 = 8738964

Showing the first eight; more decompositions exist.
