Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142558, here are decompositions:
- 5 + 142553 = 142558
- 11 + 142547 = 142558
- 29 + 142529 = 142558
- 89 + 142469 = 142558
- 131 + 142427 = 142558
- 137 + 142421 = 142558
- 167 + 142391 = 142558
- 239 + 142319 = 142558
Showing the first eight; more decompositions exist.
