Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99120, here are decompositions:
- 11 + 99109 = 99120
- 17 + 99103 = 99120
- 31 + 99089 = 99120
- 37 + 99083 = 99120
- 41 + 99079 = 99120
- 67 + 99053 = 99120
- 79 + 99041 = 99120
- 97 + 99023 = 99120
Showing the first eight; more decompositions exist.
