Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86420, here are decompositions:

7 + 86413 = 86420
31 + 86389 = 86420
67 + 86353 = 86420
79 + 86341 = 86420
97 + 86323 = 86420
109 + 86311 = 86420
127 + 86293 = 86420
151 + 86269 = 86420

Showing the first eight; more decompositions exist.
