Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155514, here are decompositions:

5 + 155509 = 155514
13 + 155501 = 155514
41 + 155473 = 155514
53 + 155461 = 155514
61 + 155453 = 155514
71 + 155443 = 155514
101 + 155413 = 155514
127 + 155387 = 155514

Showing the first eight; more decompositions exist.
