Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531698, here are decompositions:

31 + 531667 = 531698
61 + 531637 = 531698
67 + 531631 = 531698
109 + 531589 = 531698
127 + 531571 = 531698
151 + 531547 = 531698
241 + 531457 = 531698
367 + 531331 = 531698

Showing the first eight; more decompositions exist.
