Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 183918, here are decompositions:
- 11 + 183907 = 183918
- 37 + 183881 = 183918
- 41 + 183877 = 183918
- 47 + 183871 = 183918
- 89 + 183829 = 183918
- 109 + 183809 = 183918
- 157 + 183761 = 183918
- 211 + 183707 = 183918
Showing the first eight; more decompositions exist.
