Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155106, here are decompositions:

19 + 155087 = 155106
23 + 155083 = 155106
37 + 155069 = 155106
59 + 155047 = 155106
79 + 155027 = 155106
89 + 155017 = 155106
97 + 155009 = 155106
103 + 155003 = 155106

Showing the first eight; more decompositions exist.
