Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75664, here are decompositions:

5 + 75659 = 75664
11 + 75653 = 75664
23 + 75641 = 75664
47 + 75617 = 75664
53 + 75611 = 75664
107 + 75557 = 75664
131 + 75533 = 75664
137 + 75527 = 75664

Showing the first eight; more decompositions exist.
