Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 135612, here are decompositions:

5 + 135607 = 135612
11 + 135601 = 135612
13 + 135599 = 135612
19 + 135593 = 135612
23 + 135589 = 135612
31 + 135581 = 135612
41 + 135571 = 135612
53 + 135559 = 135612

Showing the first eight; more decompositions exist.
