Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142894, here are decompositions:
- 23 + 142871 = 142894
- 53 + 142841 = 142894
- 83 + 142811 = 142894
- 107 + 142787 = 142894
- 137 + 142757 = 142894
- 197 + 142697 = 142894
- 293 + 142601 = 142894
- 347 + 142547 = 142894
Showing the first eight; more decompositions exist.
