Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77402, here are decompositions:

19 + 77383 = 77402
43 + 77359 = 77402
79 + 77323 = 77402
139 + 77263 = 77402
163 + 77239 = 77402
211 + 77191 = 77402
373 + 77029 = 77402
379 + 77023 = 77402

Showing the first eight; more decompositions exist.
