Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530242, here are decompositions:

5 + 530237 = 530242
59 + 530183 = 530242
113 + 530129 = 530242
149 + 530093 = 530242
179 + 530063 = 530242
191 + 530051 = 530242
263 + 529979 = 530242
269 + 529973 = 530242

Showing the first eight; more decompositions exist.
