Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 524800, here are decompositions:

11 + 524789 = 524800
131 + 524669 = 524800
167 + 524633 = 524800
281 + 524519 = 524800
293 + 524507 = 524800
347 + 524453 = 524800
389 + 524411 = 524800
431 + 524369 = 524800

Showing the first eight; more decompositions exist.
