Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11912, here are decompositions:
- 3 + 11909 = 11912
- 73 + 11839 = 11912
- 79 + 11833 = 11912
- 181 + 11731 = 11912
- 193 + 11719 = 11912
- 211 + 11701 = 11912
- 223 + 11689 = 11912
- 409 + 11503 = 11912
Showing the first eight; more decompositions exist.
