Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28586, here are decompositions:

7 + 28579 = 28586
13 + 28573 = 28586
37 + 28549 = 28586
73 + 28513 = 28586
109 + 28477 = 28586
139 + 28447 = 28586
157 + 28429 = 28586
193 + 28393 = 28586

Showing the first eight; more decompositions exist.
