Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513236, here are decompositions:

67 + 513169 = 513236
79 + 513157 = 513236
127 + 513109 = 513236
223 + 513013 = 513236
277 + 512959 = 513236
307 + 512929 = 513236
337 + 512899 = 513236
433 + 512803 = 513236

Showing the first eight; more decompositions exist.
