Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155892, here are decompositions:

5 + 155887 = 155892
29 + 155863 = 155892
31 + 155861 = 155892
41 + 155851 = 155892
43 + 155849 = 155892
59 + 155833 = 155892
71 + 155821 = 155892
83 + 155809 = 155892

Showing the first eight; more decompositions exist.
