Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78554, here are decompositions:

13 + 78541 = 78554
37 + 78517 = 78554
43 + 78511 = 78554
67 + 78487 = 78554
127 + 78427 = 78554
271 + 78283 = 78554
277 + 78277 = 78554
313 + 78241 = 78554

Showing the first eight; more decompositions exist.
