Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72946, here are decompositions:

23 + 72923 = 72946
53 + 72893 = 72946
149 + 72797 = 72946
179 + 72767 = 72946
227 + 72719 = 72946
239 + 72707 = 72946
257 + 72689 = 72946
443 + 72503 = 72946

Showing the first eight; more decompositions exist.
