Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64722, here are decompositions:
- 5 + 64717 = 64722
- 13 + 64709 = 64722
- 29 + 64693 = 64722
- 43 + 64679 = 64722
- 59 + 64663 = 64722
- 61 + 64661 = 64722
- 89 + 64633 = 64722
- 101 + 64621 = 64722
Showing the first eight; more decompositions exist.
