Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61528, here are decompositions:

17 + 61511 = 61528
41 + 61487 = 61528
59 + 61469 = 61528
149 + 61379 = 61528
197 + 61331 = 61528
317 + 61211 = 61528
359 + 61169 = 61528
521 + 61007 = 61528

Showing the first eight; more decompositions exist.
