Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541382, here are decompositions:
- 23 + 31541359 = 31541382
- 101 + 31541281 = 31541382
- 113 + 31541269 = 31541382
- 139 + 31541243 = 31541382
- 149 + 31541233 = 31541382
- 241 + 31541141 = 31541382
- 269 + 31541113 = 31541382
- 281 + 31541101 = 31541382
Showing the first eight; more decompositions exist.
