Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 524818, here are decompositions:

17 + 524801 = 524818
29 + 524789 = 524818
137 + 524681 = 524818
149 + 524669 = 524818
227 + 524591 = 524818
311 + 524507 = 524818
389 + 524429 = 524818
431 + 524387 = 524818

Showing the first eight; more decompositions exist.
