Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526218, here are decompositions:
- 5 + 31526213 = 31526218
- 11 + 31526207 = 31526218
- 29 + 31526189 = 31526218
- 131 + 31526087 = 31526218
- 149 + 31526069 = 31526218
- 167 + 31526051 = 31526218
- 197 + 31526021 = 31526218
- 401 + 31525817 = 31526218
Showing the first eight; more decompositions exist.
