Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84112, here are decompositions:

23 + 84089 = 84112
53 + 84059 = 84112
59 + 84053 = 84112
101 + 84011 = 84112
173 + 83939 = 84112
179 + 83933 = 84112
191 + 83921 = 84112
239 + 83873 = 84112

Showing the first eight; more decompositions exist.
