Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64180, here are decompositions:

23 + 64157 = 64180
29 + 64151 = 64180
71 + 64109 = 64180
89 + 64091 = 64180
113 + 64067 = 64180
167 + 64013 = 64180
173 + 64007 = 64180
251 + 63929 = 64180

Showing the first eight; more decompositions exist.
