Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531098, here are decompositions:

19 + 531079 = 531098
109 + 530989 = 531098
151 + 530947 = 531098
229 + 530869 = 531098
241 + 530857 = 531098
331 + 530767 = 531098
367 + 530731 = 531098
397 + 530701 = 531098

Showing the first eight; more decompositions exist.
