Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42664, here are decompositions:
- 23 + 42641 = 42664
- 53 + 42611 = 42664
- 107 + 42557 = 42664
- 131 + 42533 = 42664
- 173 + 42491 = 42664
- 191 + 42473 = 42664
- 197 + 42467 = 42664
- 227 + 42437 = 42664
Showing the first eight; more decompositions exist.
