Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 69500, here are decompositions:

3 + 69497 = 69500
7 + 69493 = 69500
19 + 69481 = 69500
37 + 69463 = 69500
43 + 69457 = 69500
61 + 69439 = 69500
73 + 69427 = 69500
97 + 69403 = 69500

Showing the first eight; more decompositions exist.
