Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520242, here are decompositions:

29 + 520213 = 520242
113 + 520129 = 520242
131 + 520111 = 520242
139 + 520103 = 520242
179 + 520063 = 520242
199 + 520043 = 520242
211 + 520031 = 520242
223 + 520019 = 520242

Showing the first eight; more decompositions exist.
