Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531898, here are decompositions:

41 + 531857 = 531898
71 + 531827 = 531898
167 + 531731 = 531898
197 + 531701 = 531898
317 + 531581 = 531898
347 + 531551 = 531898
401 + 531497 = 531898
599 + 531299 = 531898

Showing the first eight; more decompositions exist.
