Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78620, here are decompositions:

13 + 78607 = 78620
37 + 78583 = 78620
43 + 78577 = 78620
67 + 78553 = 78620
79 + 78541 = 78620
103 + 78517 = 78620
109 + 78511 = 78620
181 + 78439 = 78620

Showing the first eight; more decompositions exist.
