Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78878, here are decompositions:

97 + 78781 = 78878
157 + 78721 = 78878
181 + 78697 = 78878
229 + 78649 = 78878
271 + 78607 = 78878
307 + 78571 = 78878
337 + 78541 = 78878
367 + 78511 = 78878

Showing the first eight; more decompositions exist.
