Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 37942, here are decompositions:
- 53 + 37889 = 37942
- 71 + 37871 = 37942
- 89 + 37853 = 37942
- 131 + 37811 = 37942
- 251 + 37691 = 37942
- 293 + 37649 = 37942
- 353 + 37589 = 37942
- 431 + 37511 = 37942
Showing the first eight; more decompositions exist.
