Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86372, here are decompositions:

3 + 86369 = 86372
19 + 86353 = 86372
31 + 86341 = 86372
61 + 86311 = 86372
79 + 86293 = 86372
103 + 86269 = 86372
109 + 86263 = 86372
163 + 86209 = 86372

Showing the first eight; more decompositions exist.
