Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85958, here are decompositions:

127 + 85831 = 85958
139 + 85819 = 85958
241 + 85717 = 85958
331 + 85627 = 85958
337 + 85621 = 85958
409 + 85549 = 85958
547 + 85411 = 85958
577 + 85381 = 85958

Showing the first eight; more decompositions exist.
