Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43172, here are decompositions:

13 + 43159 = 43172
79 + 43093 = 43172
109 + 43063 = 43172
193 + 42979 = 43172
211 + 42961 = 43172
229 + 42943 = 43172
271 + 42901 = 43172
313 + 42859 = 43172

Showing the first eight; more decompositions exist.
