Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585916, here are decompositions:
- 13 + 31585903 = 31585916
- 67 + 31585849 = 31585916
- 79 + 31585837 = 31585916
- 139 + 31585777 = 31585916
- 337 + 31585579 = 31585916
- 367 + 31585549 = 31585916
- 379 + 31585537 = 31585916
- 457 + 31585459 = 31585916
Showing the first eight; more decompositions exist.
