Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155712, here are decompositions:

5 + 155707 = 155712
13 + 155699 = 155712
19 + 155693 = 155712
23 + 155689 = 155712
41 + 155671 = 155712
59 + 155653 = 155712
103 + 155609 = 155712
113 + 155599 = 155712

Showing the first eight; more decompositions exist.
