Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105142, here are decompositions:
- 5 + 105137 = 105142
- 71 + 105071 = 105142
- 251 + 104891 = 105142
- 263 + 104879 = 105142
- 293 + 104849 = 105142
- 311 + 104831 = 105142
- 353 + 104789 = 105142
- 383 + 104759 = 105142
Showing the first eight; more decompositions exist.
