Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530142, here are decompositions:

5 + 530137 = 530142
13 + 530129 = 530142
79 + 530063 = 530142
101 + 530041 = 530142
163 + 529979 = 530142
181 + 529961 = 530142
271 + 529871 = 530142
313 + 529829 = 530142

Showing the first eight; more decompositions exist.
