Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99680, here are decompositions:
- 13 + 99667 = 99680
- 19 + 99661 = 99680
- 37 + 99643 = 99680
- 73 + 99607 = 99680
- 103 + 99577 = 99680
- 109 + 99571 = 99680
- 151 + 99529 = 99680
- 157 + 99523 = 99680
Showing the first eight; more decompositions exist.
