Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61574, here are decompositions:

13 + 61561 = 61574
31 + 61543 = 61574
67 + 61507 = 61574
103 + 61471 = 61574
157 + 61417 = 61574
193 + 61381 = 61574
211 + 61363 = 61574
241 + 61333 = 61574

Showing the first eight; more decompositions exist.
