Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72970, here are decompositions:

11 + 72959 = 72970
17 + 72953 = 72970
47 + 72923 = 72970
59 + 72911 = 72970
101 + 72869 = 72970
173 + 72797 = 72970
251 + 72719 = 72970
263 + 72707 = 72970

Showing the first eight; more decompositions exist.
