Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15878, here are decompositions:

19 + 15859 = 15878
61 + 15817 = 15878
139 + 15739 = 15878
151 + 15727 = 15878
199 + 15679 = 15878
211 + 15667 = 15878
229 + 15649 = 15878
271 + 15607 = 15878

Showing the first eight; more decompositions exist.
