Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86542, here are decompositions:

3 + 86539 = 86542
11 + 86531 = 86542
41 + 86501 = 86542
89 + 86453 = 86542
101 + 86441 = 86542
173 + 86369 = 86542
191 + 86351 = 86542
251 + 86291 = 86542

Showing the first eight; more decompositions exist.
