Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25042, here are decompositions:
- 5 + 25037 = 25042
- 11 + 25031 = 25042
- 29 + 25013 = 25042
- 53 + 24989 = 25042
- 71 + 24971 = 25042
- 89 + 24953 = 25042
- 191 + 24851 = 25042
- 233 + 24809 = 25042
Showing the first eight; more decompositions exist.
