Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78830, here are decompositions:

7 + 78823 = 78830
43 + 78787 = 78830
109 + 78721 = 78830
139 + 78691 = 78830
181 + 78649 = 78830
223 + 78607 = 78830
277 + 78553 = 78830
313 + 78517 = 78830

Showing the first eight; more decompositions exist.
