Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83978, here are decompositions:

67 + 83911 = 83978
109 + 83869 = 83978
241 + 83737 = 83978
277 + 83701 = 83978
337 + 83641 = 83978
421 + 83557 = 83978
541 + 83437 = 83978
547 + 83431 = 83978

Showing the first eight; more decompositions exist.
