Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78444, here are decompositions:

5 + 78439 = 78444
7 + 78437 = 78444
17 + 78427 = 78444
43 + 78401 = 78444
97 + 78347 = 78444
103 + 78341 = 78444
127 + 78317 = 78444
137 + 78307 = 78444

Showing the first eight; more decompositions exist.
