Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520186, here are decompositions:

83 + 520103 = 520186
113 + 520073 = 520186
167 + 520019 = 520186
197 + 519989 = 520186
239 + 519947 = 520186
263 + 519923 = 520186
269 + 519917 = 520186
383 + 519803 = 520186

Showing the first eight; more decompositions exist.
