Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17912, here are decompositions:
- 3 + 17909 = 17912
- 31 + 17881 = 17912
- 61 + 17851 = 17912
- 73 + 17839 = 17912
- 151 + 17761 = 17912
- 163 + 17749 = 17912
- 199 + 17713 = 17912
- 229 + 17683 = 17912
Showing the first eight; more decompositions exist.
