Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981342, here are decompositions:
- 23 + 981319 = 981342
- 31 + 981311 = 981342
- 41 + 981301 = 981342
- 53 + 981289 = 981342
- 59 + 981283 = 981342
- 71 + 981271 = 981342
- 79 + 981263 = 981342
- 101 + 981241 = 981342
Showing the first eight; more decompositions exist.
