Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 124678, here are decompositions:
- 5 + 124673 = 124678
- 101 + 124577 = 124678
- 137 + 124541 = 124678
- 149 + 124529 = 124678
- 251 + 124427 = 124678
- 311 + 124367 = 124678
- 401 + 124277 = 124678
- 431 + 124247 = 124678
Showing the first eight; more decompositions exist.
