Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 69520, here are decompositions:

23 + 69497 = 69520
29 + 69491 = 69520
47 + 69473 = 69520
53 + 69467 = 69520
89 + 69431 = 69520
131 + 69389 = 69520
137 + 69383 = 69520
149 + 69371 = 69520

Showing the first eight; more decompositions exist.
