Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2532, here are decompositions:

11 + 2521 = 2532
29 + 2503 = 2532
59 + 2473 = 2532
73 + 2459 = 2532
109 + 2423 = 2532
139 + 2393 = 2532
149 + 2383 = 2532
151 + 2381 = 2532

Showing the first eight; more decompositions exist.
