Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531004, here are decompositions:

107 + 530897 = 531004
167 + 530837 = 531004
197 + 530807 = 531004
251 + 530753 = 531004
263 + 530741 = 531004
293 + 530711 = 531004
311 + 530693 = 531004
401 + 530603 = 531004

Showing the first eight; more decompositions exist.
