Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531612, here are decompositions:

23 + 531589 = 531612
31 + 531581 = 531612
41 + 531571 = 531612
43 + 531569 = 531612
61 + 531551 = 531612
131 + 531481 = 531612
229 + 531383 = 531612
269 + 531343 = 531612

Showing the first eight; more decompositions exist.
