Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142958, here are decompositions:
- 19 + 142939 = 142958
- 61 + 142897 = 142958
- 199 + 142759 = 142958
- 349 + 142609 = 142958
- 367 + 142591 = 142958
- 421 + 142537 = 142958
- 457 + 142501 = 142958
- 577 + 142381 = 142958
Showing the first eight; more decompositions exist.
