Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80078, here are decompositions:

7 + 80071 = 80078
79 + 79999 = 80078
139 + 79939 = 80078
211 + 79867 = 80078
277 + 79801 = 80078
379 + 79699 = 80078
409 + 79669 = 80078
421 + 79657 = 80078

Showing the first eight; more decompositions exist.
