Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3742, here are decompositions:
- 3 + 3739 = 3742
- 23 + 3719 = 3742
- 41 + 3701 = 3742
- 71 + 3671 = 3742
- 83 + 3659 = 3742
- 149 + 3593 = 3742
- 251 + 3491 = 3742
- 281 + 3461 = 3742
Showing the first eight; more decompositions exist.
