Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1960, here are decompositions:
- 11 + 1949 = 1960
- 29 + 1931 = 1960
- 47 + 1913 = 1960
- 53 + 1907 = 1960
- 59 + 1901 = 1960
- 71 + 1889 = 1960
- 83 + 1877 = 1960
- 89 + 1871 = 1960
Showing the first eight; more decompositions exist.
