Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9972, here are decompositions:
- 5 + 9967 = 9972
- 23 + 9949 = 9972
- 31 + 9941 = 9972
- 41 + 9931 = 9972
- 43 + 9929 = 9972
- 71 + 9901 = 9972
- 89 + 9883 = 9972
- 101 + 9871 = 9972
Showing the first eight; more decompositions exist.
