Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513850, here are decompositions:

11 + 513839 = 513850
83 + 513767 = 513850
89 + 513761 = 513850
101 + 513749 = 513850
131 + 513719 = 513850
167 + 513683 = 513850
257 + 513593 = 513850
317 + 513533 = 513850

Showing the first eight; more decompositions exist.
