Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78104, here are decompositions:

3 + 78101 = 78104
73 + 78031 = 78104
97 + 78007 = 78104
127 + 77977 = 78104
211 + 77893 = 78104
241 + 77863 = 78104
307 + 77797 = 78104
331 + 77773 = 78104

Showing the first eight; more decompositions exist.
