Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18770, here are decompositions:
- 13 + 18757 = 18770
- 79 + 18691 = 18770
- 109 + 18661 = 18770
- 229 + 18541 = 18770
- 277 + 18493 = 18770
- 313 + 18457 = 18770
- 331 + 18439 = 18770
- 337 + 18433 = 18770
Showing the first eight; more decompositions exist.
