Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86842, here are decompositions:

5 + 86837 = 86842
29 + 86813 = 86842
59 + 86783 = 86842
71 + 86771 = 86842
89 + 86753 = 86842
113 + 86729 = 86842
131 + 86711 = 86842
149 + 86693 = 86842

Showing the first eight; more decompositions exist.
