Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 37980, here are decompositions:
- 13 + 37967 = 37980
- 17 + 37963 = 37980
- 23 + 37957 = 37980
- 29 + 37951 = 37980
- 73 + 37907 = 37980
- 83 + 37897 = 37980
- 101 + 37879 = 37980
- 109 + 37871 = 37980
Showing the first eight; more decompositions exist.
