Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155480, here are decompositions:

7 + 155473 = 155480
19 + 155461 = 155480
37 + 155443 = 155480
67 + 155413 = 155480
97 + 155383 = 155480
103 + 155377 = 155480
109 + 155371 = 155480
163 + 155317 = 155480

Showing the first eight; more decompositions exist.
