Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11570, here are decompositions:
- 19 + 11551 = 11570
- 43 + 11527 = 11570
- 67 + 11503 = 11570
- 73 + 11497 = 11570
- 79 + 11491 = 11570
- 103 + 11467 = 11570
- 127 + 11443 = 11570
- 241 + 11329 = 11570
Showing the first eight; more decompositions exist.
