Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531708, here are decompositions:

7 + 531701 = 531708
19 + 531689 = 531708
41 + 531667 = 531708
71 + 531637 = 531708
97 + 531611 = 531708
127 + 531581 = 531708
137 + 531571 = 531708
139 + 531569 = 531708

Showing the first eight; more decompositions exist.
