Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021342, here are decompositions:
- 11 + 1021331 = 1021342
- 41 + 1021301 = 1021342
- 53 + 1021289 = 1021342
- 59 + 1021283 = 1021342
- 71 + 1021271 = 1021342
- 83 + 1021259 = 1021342
- 89 + 1021253 = 1021342
- 251 + 1021091 = 1021342
Showing the first eight; more decompositions exist.
