Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122758, here are decompositions:
- 5 + 122753 = 122758
- 17 + 122741 = 122758
- 107 + 122651 = 122758
- 149 + 122609 = 122758
- 179 + 122579 = 122758
- 197 + 122561 = 122758
- 257 + 122501 = 122758
- 269 + 122489 = 122758
Showing the first eight; more decompositions exist.
