Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11972, here are decompositions:
- 3 + 11969 = 11972
- 13 + 11959 = 11972
- 19 + 11953 = 11972
- 31 + 11941 = 11972
- 109 + 11863 = 11972
- 139 + 11833 = 11972
- 151 + 11821 = 11972
- 193 + 11779 = 11972
Showing the first eight; more decompositions exist.
