Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77282, here are decompositions:

3 + 77279 = 77282
13 + 77269 = 77282
19 + 77263 = 77282
43 + 77239 = 77282
181 + 77101 = 77282
241 + 77041 = 77282
409 + 76873 = 77282
463 + 76819 = 77282

Showing the first eight; more decompositions exist.
