Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530148, here are decompositions:

5 + 530143 = 530148
11 + 530137 = 530148
19 + 530129 = 530148
61 + 530087 = 530148
97 + 530051 = 530148
107 + 530041 = 530148
127 + 530021 = 530148
131 + 530017 = 530148

Showing the first eight; more decompositions exist.
