Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534902, here are decompositions:
- 23 + 31534879 = 31534902
- 29 + 31534873 = 31534902
- 31 + 31534871 = 31534902
- 71 + 31534831 = 31534902
- 83 + 31534819 = 31534902
- 101 + 31534801 = 31534902
- 103 + 31534799 = 31534902
- 149 + 31534753 = 31534902
Showing the first eight; more decompositions exist.
