Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9938, here are decompositions:
- 7 + 9931 = 9938
- 31 + 9907 = 9938
- 37 + 9901 = 9938
- 67 + 9871 = 9938
- 79 + 9859 = 9938
- 109 + 9829 = 9938
- 127 + 9811 = 9938
- 151 + 9787 = 9938
Showing the first eight; more decompositions exist.
