Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1924, here are decompositions:
- 11 + 1913 = 1924
- 17 + 1907 = 1924
- 23 + 1901 = 1924
- 47 + 1877 = 1924
- 53 + 1871 = 1924
- 101 + 1823 = 1924
- 113 + 1811 = 1924
- 137 + 1787 = 1924
Showing the first eight; more decompositions exist.
