Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142298, here are decompositions:
- 61 + 142237 = 142298
- 67 + 142231 = 142298
- 109 + 142189 = 142298
- 139 + 142159 = 142298
- 199 + 142099 = 142298
- 241 + 142057 = 142298
- 307 + 141991 = 142298
- 337 + 141961 = 142298
Showing the first eight; more decompositions exist.
