Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86212, here are decompositions:

3 + 86209 = 86212
11 + 86201 = 86212
29 + 86183 = 86212
41 + 86171 = 86212
101 + 86111 = 86212
281 + 85931 = 86212
359 + 85853 = 86212
383 + 85829 = 86212

Showing the first eight; more decompositions exist.
