Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541184, here are decompositions:
- 5 + 31541179 = 31541184
- 11 + 31541173 = 31541184
- 23 + 31541161 = 31541184
- 43 + 31541141 = 31541184
- 67 + 31541117 = 31541184
- 71 + 31541113 = 31541184
- 83 + 31541101 = 31541184
- 113 + 31541071 = 31541184
Showing the first eight; more decompositions exist.
