Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530520, here are decompositions:

7 + 530513 = 530520
13 + 530507 = 530520
19 + 530501 = 530520
73 + 530447 = 530520
127 + 530393 = 530520
131 + 530389 = 530520
167 + 530353 = 530520
181 + 530339 = 530520

Showing the first eight; more decompositions exist.
