Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526154, here are decompositions:
- 13 + 31526141 = 31526154
- 67 + 31526087 = 31526154
- 71 + 31526083 = 31526154
- 97 + 31526057 = 31526154
- 103 + 31526051 = 31526154
- 173 + 31525981 = 31526154
- 197 + 31525957 = 31526154
- 227 + 31525927 = 31526154
Showing the first eight; more decompositions exist.
