Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72434, here are decompositions:

3 + 72431 = 72434
13 + 72421 = 72434
67 + 72367 = 72434
97 + 72337 = 72434
127 + 72307 = 72434
157 + 72277 = 72434
163 + 72271 = 72434
181 + 72253 = 72434

Showing the first eight; more decompositions exist.
