Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38172, here are decompositions:

5 + 38167 = 38172
19 + 38153 = 38172
23 + 38149 = 38172
53 + 38119 = 38172
59 + 38113 = 38172
89 + 38083 = 38172
103 + 38069 = 38172
179 + 37993 = 38172

Showing the first eight; more decompositions exist.
