Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61564, here are decompositions:

3 + 61561 = 61564
5 + 61559 = 61564
11 + 61553 = 61564
17 + 61547 = 61564
53 + 61511 = 61564
71 + 61493 = 61564
101 + 61463 = 61564
233 + 61331 = 61564

Showing the first eight; more decompositions exist.
