Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86444, here are decompositions:

3 + 86441 = 86444
31 + 86413 = 86444
73 + 86371 = 86444
103 + 86341 = 86444
151 + 86293 = 86444
157 + 86287 = 86444
181 + 86263 = 86444
283 + 86161 = 86444

Showing the first eight; more decompositions exist.
