Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1942, here are decompositions:
- 11 + 1931 = 1942
- 29 + 1913 = 1942
- 41 + 1901 = 1942
- 53 + 1889 = 1942
- 71 + 1871 = 1942
- 131 + 1811 = 1942
- 233 + 1709 = 1942
- 359 + 1583 = 1942
Showing the first eight; more decompositions exist.
