Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42998, here are decompositions:
- 19 + 42979 = 42998
- 31 + 42967 = 42998
- 37 + 42961 = 42998
- 61 + 42937 = 42998
- 97 + 42901 = 42998
- 139 + 42859 = 42998
- 157 + 42841 = 42998
- 211 + 42787 = 42998
Showing the first eight; more decompositions exist.
