Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61558, here are decompositions:

5 + 61553 = 61558
11 + 61547 = 61558
47 + 61511 = 61558
71 + 61487 = 61558
89 + 61469 = 61558
149 + 61409 = 61558
179 + 61379 = 61558
227 + 61331 = 61558

Showing the first eight; more decompositions exist.
