Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42990, here are decompositions:
- 11 + 42979 = 42990
- 23 + 42967 = 42990
- 29 + 42961 = 42990
- 37 + 42953 = 42990
- 47 + 42943 = 42990
- 53 + 42937 = 42990
- 61 + 42929 = 42990
- 67 + 42923 = 42990
Showing the first eight; more decompositions exist.
