Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12020, here are decompositions:
- 13 + 12007 = 12020
- 61 + 11959 = 12020
- 67 + 11953 = 12020
- 79 + 11941 = 12020
- 97 + 11923 = 12020
- 157 + 11863 = 12020
- 181 + 11839 = 12020
- 193 + 11827 = 12020
Showing the first eight; more decompositions exist.
