Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530278, here are decompositions:

11 + 530267 = 530278
17 + 530261 = 530278
29 + 530249 = 530278
41 + 530237 = 530278
101 + 530177 = 530278
149 + 530129 = 530278
191 + 530087 = 530278
227 + 530051 = 530278

Showing the first eight; more decompositions exist.
