Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77430, here are decompositions:

11 + 77419 = 77430
13 + 77417 = 77430
47 + 77383 = 77430
53 + 77377 = 77430
61 + 77369 = 77430
71 + 77359 = 77430
79 + 77351 = 77430
83 + 77347 = 77430

Showing the first eight; more decompositions exist.
