Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155568, here are decompositions:

11 + 155557 = 155568
29 + 155539 = 155568
31 + 155537 = 155568
47 + 155521 = 155568
59 + 155509 = 155568
67 + 155501 = 155568
107 + 155461 = 155568
181 + 155387 = 155568

Showing the first eight; more decompositions exist.
