Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520238, here are decompositions:

109 + 520129 = 520238
127 + 520111 = 520238
241 + 519997 = 520238
307 + 519931 = 520238
331 + 519907 = 520238
349 + 519889 = 520238
421 + 519817 = 520238
547 + 519691 = 520238

Showing the first eight; more decompositions exist.
