Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155676, here are decompositions:

5 + 155671 = 155676
13 + 155663 = 155676
19 + 155657 = 155676
23 + 155653 = 155676
67 + 155609 = 155676
83 + 155593 = 155676
97 + 155579 = 155676
107 + 155569 = 155676

Showing the first eight; more decompositions exist.
