Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102664, here are decompositions:

11 + 102653 = 102664
17 + 102647 = 102664
53 + 102611 = 102664
71 + 102593 = 102664
101 + 102563 = 102664
113 + 102551 = 102664
131 + 102533 = 102664
167 + 102497 = 102664

Showing the first eight; more decompositions exist.
