Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155826, here are decompositions:

5 + 155821 = 155826
17 + 155809 = 155826
29 + 155797 = 155826
43 + 155783 = 155826
53 + 155773 = 155826
79 + 155747 = 155826
103 + 155723 = 155826
107 + 155719 = 155826

Showing the first eight; more decompositions exist.
