Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85542, here are decompositions:

11 + 85531 = 85542
19 + 85523 = 85542
29 + 85513 = 85542
73 + 85469 = 85542
89 + 85453 = 85542
103 + 85439 = 85542
113 + 85429 = 85542
131 + 85411 = 85542

Showing the first eight; more decompositions exist.
