Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 524728, here are decompositions:

47 + 524681 = 524728
59 + 524669 = 524728
137 + 524591 = 524728
317 + 524411 = 524728
359 + 524369 = 524728
419 + 524309 = 524728
467 + 524261 = 524728
509 + 524219 = 524728

Showing the first eight; more decompositions exist.
