Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531746, here are decompositions:

73 + 531673 = 531746
79 + 531667 = 531746
109 + 531637 = 531746
157 + 531589 = 531746
199 + 531547 = 531746
409 + 531337 = 531746
577 + 531169 = 531746
613 + 531133 = 531746

Showing the first eight; more decompositions exist.
