Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531770, here are decompositions:

97 + 531673 = 531770
103 + 531667 = 531770
139 + 531631 = 531770
157 + 531613 = 531770
181 + 531589 = 531770
199 + 531571 = 531770
223 + 531547 = 531770
313 + 531457 = 531770

Showing the first eight; more decompositions exist.
