Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42556, here are decompositions:
- 23 + 42533 = 42556
- 47 + 42509 = 42556
- 83 + 42473 = 42556
- 89 + 42467 = 42556
- 113 + 42443 = 42556
- 149 + 42407 = 42556
- 197 + 42359 = 42556
- 233 + 42323 = 42556
Showing the first eight; more decompositions exist.
