Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12874, here are decompositions:
- 53 + 12821 = 12874
- 83 + 12791 = 12874
- 131 + 12743 = 12874
- 227 + 12647 = 12874
- 233 + 12641 = 12874
- 263 + 12611 = 12874
- 347 + 12527 = 12874
- 383 + 12491 = 12874
Showing the first eight; more decompositions exist.
