Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155004, here are decompositions:

13 + 154991 = 155004
23 + 154981 = 155004
61 + 154943 = 155004
67 + 154937 = 155004
71 + 154933 = 155004
107 + 154897 = 155004
127 + 154877 = 155004
131 + 154873 = 155004

Showing the first eight; more decompositions exist.
