Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137842, here are decompositions:
- 11 + 137831 = 137842
- 71 + 137771 = 137842
- 269 + 137573 = 137842
- 359 + 137483 = 137842
- 389 + 137453 = 137842
- 443 + 137399 = 137842
- 449 + 137393 = 137842
- 479 + 137363 = 137842
Showing the first eight; more decompositions exist.
