Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531020, here are decompositions:
- 19 + 31531001 = 31531020
- 41 + 31530979 = 31531020
- 43 + 31530977 = 31531020
- 47 + 31530973 = 31531020
- 61 + 31530959 = 31531020
- 127 + 31530893 = 31531020
- 179 + 31530841 = 31531020
- 193 + 31530827 = 31531020
Showing the first eight; more decompositions exist.
