Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526440, here are decompositions:
- 17 + 31526423 = 31526440
- 53 + 31526387 = 31526440
- 89 + 31526351 = 31526440
- 167 + 31526273 = 31526440
- 227 + 31526213 = 31526440
- 233 + 31526207 = 31526440
- 251 + 31526189 = 31526440
- 353 + 31526087 = 31526440
Showing the first eight; more decompositions exist.
