Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30542, here are decompositions:

3 + 30539 = 30542
13 + 30529 = 30542
73 + 30469 = 30542
139 + 30403 = 30542
151 + 30391 = 30542
223 + 30319 = 30542
229 + 30313 = 30542
271 + 30271 = 30542

Showing the first eight; more decompositions exist.
