Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534160, here are decompositions:
- 19 + 31534141 = 31534160
- 43 + 31534117 = 31534160
- 103 + 31534057 = 31534160
- 109 + 31534051 = 31534160
- 127 + 31534033 = 31534160
- 181 + 31533979 = 31534160
- 193 + 31533967 = 31534160
- 211 + 31533949 = 31534160
Showing the first eight; more decompositions exist.
