Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99720, here are decompositions:
- 7 + 99713 = 99720
- 11 + 99709 = 99720
- 13 + 99707 = 99720
- 31 + 99689 = 99720
- 41 + 99679 = 99720
- 53 + 99667 = 99720
- 59 + 99661 = 99720
- 97 + 99623 = 99720
Showing the first eight; more decompositions exist.
