Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72976, here are decompositions:

3 + 72973 = 72976
17 + 72959 = 72976
23 + 72953 = 72976
53 + 72923 = 72976
83 + 72893 = 72976
107 + 72869 = 72976
179 + 72797 = 72976
257 + 72719 = 72976

Showing the first eight; more decompositions exist.
