Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2038, here are decompositions:
- 11 + 2027 = 2038
- 41 + 1997 = 2038
- 59 + 1979 = 2038
- 89 + 1949 = 2038
- 107 + 1931 = 2038
- 131 + 1907 = 2038
- 137 + 1901 = 2038
- 149 + 1889 = 2038
Showing the first eight; more decompositions exist.
