Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531104, here are decompositions:

3 + 531101 = 531104
61 + 531043 = 531104
127 + 530977 = 531104
157 + 530947 = 531104
193 + 530911 = 531104
271 + 530833 = 531104
307 + 530797 = 531104
331 + 530773 = 531104

Showing the first eight; more decompositions exist.
