Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64172, here are decompositions:

19 + 64153 = 64172
109 + 64063 = 64172
139 + 64033 = 64172
223 + 63949 = 64172
271 + 63901 = 64172
331 + 63841 = 64172
349 + 63823 = 64172
373 + 63799 = 64172

Showing the first eight; more decompositions exist.
