Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155874, here are decompositions:

11 + 155863 = 155874
13 + 155861 = 155874
23 + 155851 = 155874
41 + 155833 = 155874
53 + 155821 = 155874
73 + 155801 = 155874
97 + 155777 = 155874
101 + 155773 = 155874

Showing the first eight; more decompositions exist.
