Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8912, here are decompositions:
- 19 + 8893 = 8912
- 73 + 8839 = 8912
- 109 + 8803 = 8912
- 151 + 8761 = 8912
- 181 + 8731 = 8912
- 193 + 8719 = 8912
- 199 + 8713 = 8912
- 223 + 8689 = 8912
Showing the first eight; more decompositions exist.
