Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534136, here are decompositions:
- 19 + 31534117 = 31534136
- 79 + 31534057 = 31534136
- 103 + 31534033 = 31534136
- 157 + 31533979 = 31534136
- 307 + 31533829 = 31534136
- 313 + 31533823 = 31534136
- 367 + 31533769 = 31534136
- 373 + 31533763 = 31534136
Showing the first eight; more decompositions exist.
