Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155460, here are decompositions:

7 + 155453 = 155460
17 + 155443 = 155460
37 + 155423 = 155460
47 + 155413 = 155460
61 + 155399 = 155460
73 + 155387 = 155460
79 + 155381 = 155460
83 + 155377 = 155460

Showing the first eight; more decompositions exist.
