Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77454, here are decompositions:

7 + 77447 = 77454
23 + 77431 = 77454
37 + 77417 = 77454
71 + 77383 = 77454
103 + 77351 = 77454
107 + 77347 = 77454
131 + 77323 = 77454
137 + 77317 = 77454

Showing the first eight; more decompositions exist.
