Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531956, here are decompositions:

37 + 531919 = 531956
79 + 531877 = 531956
109 + 531847 = 531956
157 + 531799 = 531956
163 + 531793 = 531956
283 + 531673 = 531956
367 + 531589 = 531956
409 + 531547 = 531956

Showing the first eight; more decompositions exist.
