Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530240, here are decompositions:

3 + 530237 = 530240
13 + 530227 = 530240
31 + 530209 = 530240
37 + 530203 = 530240
43 + 530197 = 530240
97 + 530143 = 530240
103 + 530137 = 530240
199 + 530041 = 530240

Showing the first eight; more decompositions exist.
