Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142822, here are decompositions:
- 11 + 142811 = 142822
- 23 + 142799 = 142822
- 89 + 142733 = 142822
- 149 + 142673 = 142822
- 233 + 142589 = 142822
- 263 + 142559 = 142822
- 269 + 142553 = 142822
- 293 + 142529 = 142822
Showing the first eight; more decompositions exist.
