Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72464, here are decompositions:

3 + 72461 = 72464
43 + 72421 = 72464
97 + 72367 = 72464
127 + 72337 = 72464
151 + 72313 = 72464
157 + 72307 = 72464
193 + 72271 = 72464
211 + 72253 = 72464

Showing the first eight; more decompositions exist.
