Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541916, here are decompositions:
- 13 + 31541903 = 31541916
- 17 + 31541899 = 31541916
- 23 + 31541893 = 31541916
- 47 + 31541869 = 31541916
- 59 + 31541857 = 31541916
- 89 + 31541827 = 31541916
- 179 + 31541737 = 31541916
- 223 + 31541693 = 31541916
Showing the first eight; more decompositions exist.
