Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122818, here are decompositions:
- 29 + 122789 = 122818
- 41 + 122777 = 122818
- 167 + 122651 = 122818
- 239 + 122579 = 122818
- 257 + 122561 = 122818
- 317 + 122501 = 122818
- 347 + 122471 = 122818
- 419 + 122399 = 122818
Showing the first eight; more decompositions exist.
