Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142570, here are decompositions:
- 3 + 142567 = 142570
- 11 + 142559 = 142570
- 17 + 142553 = 142570
- 23 + 142547 = 142570
- 41 + 142529 = 142570
- 101 + 142469 = 142570
- 137 + 142433 = 142570
- 149 + 142421 = 142570
Showing the first eight; more decompositions exist.
