Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77450, here are decompositions:

3 + 77447 = 77450
19 + 77431 = 77450
31 + 77419 = 77450
67 + 77383 = 77450
73 + 77377 = 77450
103 + 77347 = 77450
127 + 77323 = 77450
181 + 77269 = 77450

Showing the first eight; more decompositions exist.
