Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142624, here are decompositions:
- 5 + 142619 = 142624
- 17 + 142607 = 142624
- 23 + 142601 = 142624
- 71 + 142553 = 142624
- 191 + 142433 = 142624
- 197 + 142427 = 142624
- 233 + 142391 = 142624
- 353 + 142271 = 142624
Showing the first eight; more decompositions exist.
