Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77482, here are decompositions:

3 + 77479 = 77482
5 + 77477 = 77482
11 + 77471 = 77482
113 + 77369 = 77482
131 + 77351 = 77482
191 + 77291 = 77482
233 + 77249 = 77482
239 + 77243 = 77482

Showing the first eight; more decompositions exist.
