Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12970, here are decompositions:
- 3 + 12967 = 12970
- 11 + 12959 = 12970
- 17 + 12953 = 12970
- 29 + 12941 = 12970
- 47 + 12923 = 12970
- 53 + 12917 = 12970
- 59 + 12911 = 12970
- 71 + 12899 = 12970
Showing the first eight; more decompositions exist.
