Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168918, here are decompositions:
- 5 + 168913 = 168918
- 17 + 168901 = 168918
- 19 + 168899 = 168918
- 31 + 168887 = 168918
- 67 + 168851 = 168918
- 137 + 168781 = 168918
- 149 + 168769 = 168918
- 157 + 168761 = 168918
Showing the first eight; more decompositions exist.
