Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72700, here are decompositions:

11 + 72689 = 72700
29 + 72671 = 72700
53 + 72647 = 72700
83 + 72617 = 72700
149 + 72551 = 72700
167 + 72533 = 72700
197 + 72503 = 72700
233 + 72467 = 72700

Showing the first eight; more decompositions exist.
