Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526904, here are decompositions:
- 5 + 31526899 = 31526904
- 11 + 31526893 = 31526904
- 23 + 31526881 = 31526904
- 41 + 31526863 = 31526904
- 113 + 31526791 = 31526904
- 127 + 31526777 = 31526904
- 131 + 31526773 = 31526904
- 151 + 31526753 = 31526904
Showing the first eight; more decompositions exist.
