Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530380, here are decompositions:

41 + 530339 = 530380
47 + 530333 = 530380
83 + 530297 = 530380
101 + 530279 = 530380
113 + 530267 = 530380
131 + 530249 = 530380
197 + 530183 = 530380
251 + 530129 = 530380

Showing the first eight; more decompositions exist.
