Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78502, here are decompositions:

5 + 78497 = 78502
23 + 78479 = 78502
101 + 78401 = 78502
191 + 78311 = 78502
269 + 78233 = 78502
311 + 78191 = 78502
401 + 78101 = 78502
443 + 78059 = 78502

Showing the first eight; more decompositions exist.
