Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25142, here are decompositions:
- 31 + 25111 = 25142
- 109 + 25033 = 25142
- 163 + 24979 = 25142
- 199 + 24943 = 25142
- 223 + 24919 = 25142
- 283 + 24859 = 25142
- 349 + 24793 = 25142
- 379 + 24763 = 25142
Showing the first eight; more decompositions exist.
