Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78558, here are decompositions:

5 + 78553 = 78558
17 + 78541 = 78558
19 + 78539 = 78558
41 + 78517 = 78558
47 + 78511 = 78558
61 + 78497 = 78558
71 + 78487 = 78558
79 + 78479 = 78558

Showing the first eight; more decompositions exist.
