Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531482, here are decompositions:

139 + 531343 = 531482
151 + 531331 = 531482
229 + 531253 = 531482
313 + 531169 = 531482
349 + 531133 = 531482
379 + 531103 = 531482
439 + 531043 = 531482
499 + 530983 = 531482

Showing the first eight; more decompositions exist.
