Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142156, here are decompositions:
- 5 + 142151 = 142156
- 59 + 142097 = 142156
- 89 + 142067 = 142156
- 107 + 142049 = 142156
- 137 + 142019 = 142156
- 149 + 142007 = 142156
- 197 + 141959 = 142156
- 239 + 141917 = 142156
Showing the first eight; more decompositions exist.
