Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78872, here are decompositions:

19 + 78853 = 78872
151 + 78721 = 78872
181 + 78691 = 78872
223 + 78649 = 78872
229 + 78643 = 78872
331 + 78541 = 78872
433 + 78439 = 78872
571 + 78301 = 78872

Showing the first eight; more decompositions exist.
