Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10442, here are decompositions:
- 13 + 10429 = 10442
- 43 + 10399 = 10442
- 73 + 10369 = 10442
- 109 + 10333 = 10442
- 139 + 10303 = 10442
- 199 + 10243 = 10442
- 283 + 10159 = 10442
- 331 + 10111 = 10442
Showing the first eight; more decompositions exist.
