Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142554, here are decompositions:

7 + 142547 = 142554
11 + 142543 = 142554
17 + 142537 = 142554
53 + 142501 = 142554
101 + 142453 = 142554
127 + 142427 = 142554
151 + 142403 = 142554
163 + 142391 = 142554

Showing the first eight; more decompositions exist.
