Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2012, here are decompositions:
- 13 + 1999 = 2012
- 19 + 1993 = 2012
- 61 + 1951 = 2012
- 79 + 1933 = 2012
- 139 + 1873 = 2012
- 151 + 1861 = 2012
- 181 + 1831 = 2012
- 211 + 1801 = 2012
Showing the first eight; more decompositions exist.
