Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86242, here are decompositions:

3 + 86239 = 86242
41 + 86201 = 86242
59 + 86183 = 86242
71 + 86171 = 86242
131 + 86111 = 86242
173 + 86069 = 86242
251 + 85991 = 86242
311 + 85931 = 86242

Showing the first eight; more decompositions exist.
