Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84186, here are decompositions:

5 + 84181 = 84186
7 + 84179 = 84186
23 + 84163 = 84186
43 + 84143 = 84186
59 + 84127 = 84186
97 + 84089 = 84186
127 + 84059 = 84186
139 + 84047 = 84186

Showing the first eight; more decompositions exist.
