Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142306, here are decompositions:
- 83 + 142223 = 142306
- 89 + 142217 = 142306
- 113 + 142193 = 142306
- 137 + 142169 = 142306
- 149 + 142157 = 142306
- 239 + 142067 = 142306
- 257 + 142049 = 142306
- 347 + 141959 = 142306
Showing the first eight; more decompositions exist.
