Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7874, here are decompositions:
- 7 + 7867 = 7874
- 151 + 7723 = 7874
- 157 + 7717 = 7874
- 193 + 7681 = 7874
- 271 + 7603 = 7874
- 283 + 7591 = 7874
- 313 + 7561 = 7874
- 337 + 7537 = 7874
Showing the first eight; more decompositions exist.
