Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526380, here are decompositions:
- 29 + 31526351 = 31526380
- 107 + 31526273 = 31526380
- 167 + 31526213 = 31526380
- 173 + 31526207 = 31526380
- 191 + 31526189 = 31526380
- 239 + 31526141 = 31526380
- 293 + 31526087 = 31526380
- 311 + 31526069 = 31526380
Showing the first eight; more decompositions exist.
