Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155850, here are decompositions:

17 + 155833 = 155850
29 + 155821 = 155850
41 + 155809 = 155850
53 + 155797 = 155850
67 + 155783 = 155850
73 + 155777 = 155850
103 + 155747 = 155850
109 + 155741 = 155850

Showing the first eight; more decompositions exist.
