Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520228, here are decompositions:

197 + 520031 = 520228
239 + 519989 = 520228
257 + 519971 = 520228
281 + 519947 = 520228
311 + 519917 = 520228
347 + 519881 = 520228
431 + 519797 = 520228
491 + 519737 = 520228

Showing the first eight; more decompositions exist.
