Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83970, here are decompositions:

31 + 83939 = 83970
37 + 83933 = 83970
59 + 83911 = 83970
67 + 83903 = 83970
79 + 83891 = 83970
97 + 83873 = 83970
101 + 83869 = 83970
113 + 83857 = 83970

Showing the first eight; more decompositions exist.
