Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532774, here are decompositions:
- 37 + 31532737 = 31532774
- 181 + 31532593 = 31532774
- 193 + 31532581 = 31532774
- 223 + 31532551 = 31532774
- 277 + 31532497 = 31532774
- 337 + 31532437 = 31532774
- 373 + 31532401 = 31532774
- 421 + 31532353 = 31532774
Showing the first eight; more decompositions exist.
