Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78202, here are decompositions:

11 + 78191 = 78202
23 + 78179 = 78202
29 + 78173 = 78202
101 + 78101 = 78202
233 + 77969 = 78202
251 + 77951 = 78202
269 + 77933 = 78202
353 + 77849 = 78202

Showing the first eight; more decompositions exist.
