Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531672, here are decompositions:

5 + 531667 = 531672
41 + 531631 = 531672
59 + 531613 = 531672
61 + 531611 = 531672
83 + 531589 = 531672
101 + 531571 = 531672
103 + 531569 = 531672
151 + 531521 = 531672

Showing the first eight; more decompositions exist.
