Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18884, here are decompositions:
- 97 + 18787 = 18884
- 127 + 18757 = 18884
- 193 + 18691 = 18884
- 223 + 18661 = 18884
- 331 + 18553 = 18884
- 367 + 18517 = 18884
- 433 + 18451 = 18884
- 457 + 18427 = 18884
Showing the first eight; more decompositions exist.
