Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187086, here are decompositions:

5 + 187081 = 187086
13 + 187073 = 187086
17 + 187069 = 187086
19 + 187067 = 187086
37 + 187049 = 187086
43 + 187043 = 187086
59 + 187027 = 187086
83 + 187003 = 187086

Showing the first eight; more decompositions exist.
