Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78902, here are decompositions:

13 + 78889 = 78902
79 + 78823 = 78902
181 + 78721 = 78902
211 + 78691 = 78902
331 + 78571 = 78902
349 + 78553 = 78902
463 + 78439 = 78902
601 + 78301 = 78902

Showing the first eight; more decompositions exist.
