Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77902, here are decompositions:

3 + 77899 = 77902
53 + 77849 = 77902
89 + 77813 = 77902
101 + 77801 = 77902
179 + 77723 = 77902
191 + 77711 = 77902
281 + 77621 = 77902
311 + 77591 = 77902

Showing the first eight; more decompositions exist.
