Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142026, here are decompositions:
- 7 + 142019 = 142026
- 19 + 142007 = 142026
- 67 + 141959 = 142026
- 89 + 141937 = 142026
- 109 + 141917 = 142026
- 163 + 141863 = 142026
- 173 + 141853 = 142026
- 193 + 141833 = 142026
Showing the first eight; more decompositions exist.
