Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 53172, here are decompositions:

11 + 53161 = 53172
23 + 53149 = 53172
43 + 53129 = 53172
59 + 53113 = 53172
71 + 53101 = 53172
79 + 53093 = 53172
83 + 53089 = 53172
103 + 53069 = 53172

Showing the first eight; more decompositions exist.
