Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99220, here are decompositions:
- 29 + 99191 = 99220
- 47 + 99173 = 99220
- 71 + 99149 = 99220
- 83 + 99137 = 99220
- 89 + 99131 = 99220
- 101 + 99119 = 99220
- 131 + 99089 = 99220
- 137 + 99083 = 99220
Showing the first eight; more decompositions exist.
