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.
