Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78318, here are decompositions:

7 + 78311 = 78318
11 + 78307 = 78318
17 + 78301 = 78318
41 + 78277 = 78318
59 + 78259 = 78318
89 + 78229 = 78318
127 + 78191 = 78318
139 + 78179 = 78318

Showing the first eight; more decompositions exist.
