Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72342, here are decompositions:

5 + 72337 = 72342
29 + 72313 = 72342
71 + 72271 = 72342
73 + 72269 = 72342
89 + 72253 = 72342
113 + 72229 = 72342
131 + 72211 = 72342
173 + 72169 = 72342

Showing the first eight; more decompositions exist.
