Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42124, here are decompositions:
- 23 + 42101 = 42124
- 41 + 42083 = 42124
- 53 + 42071 = 42124
- 101 + 42023 = 42124
- 107 + 42017 = 42124
- 167 + 41957 = 42124
- 197 + 41927 = 42124
- 227 + 41897 = 42124
Showing the first eight; more decompositions exist.
