Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87086, here are decompositions:

3 + 87083 = 87086
37 + 87049 = 87086
73 + 87013 = 87086
127 + 86959 = 87086
157 + 86929 = 87086
163 + 86923 = 87086
229 + 86857 = 87086
367 + 86719 = 87086

Showing the first eight; more decompositions exist.
