Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530138, here are decompositions:

97 + 530041 = 530138
139 + 529999 = 530138
151 + 529987 = 530138
157 + 529981 = 530138
181 + 529957 = 530138
199 + 529939 = 530138
211 + 529927 = 530138
331 + 529807 = 530138

Showing the first eight; more decompositions exist.
