Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77372, here are decompositions:

3 + 77369 = 77372
13 + 77359 = 77372
103 + 77269 = 77372
109 + 77263 = 77372
181 + 77191 = 77372
271 + 77101 = 77372
331 + 77041 = 77372
349 + 77023 = 77372

Showing the first eight; more decompositions exist.
