Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25434, here are decompositions:

11 + 25423 = 25434
23 + 25411 = 25434
43 + 25391 = 25434
61 + 25373 = 25434
67 + 25367 = 25434
113 + 25321 = 25434
127 + 25307 = 25434
131 + 25303 = 25434

Showing the first eight; more decompositions exist.
