Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86442, here are decompositions:

19 + 86423 = 86442
29 + 86413 = 86442
43 + 86399 = 86442
53 + 86389 = 86442
61 + 86381 = 86442
71 + 86371 = 86442
73 + 86369 = 86442
89 + 86353 = 86442

Showing the first eight; more decompositions exist.
