Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31742, here are decompositions:
- 13 + 31729 = 31742
- 19 + 31723 = 31742
- 43 + 31699 = 31742
- 79 + 31663 = 31742
- 199 + 31543 = 31742
- 211 + 31531 = 31742
- 229 + 31513 = 31742
- 349 + 31393 = 31742
Showing the first eight; more decompositions exist.
