Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78812, here are decompositions:

3 + 78809 = 78812
31 + 78781 = 78812
163 + 78649 = 78812
229 + 78583 = 78812
241 + 78571 = 78812
271 + 78541 = 78812
373 + 78439 = 78812
571 + 78241 = 78812

Showing the first eight; more decompositions exist.
