Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532908, here are decompositions:
- 41 + 31532867 = 31532908
- 131 + 31532777 = 31532908
- 269 + 31532639 = 31532908
- 311 + 31532597 = 31532908
- 401 + 31532507 = 31532908
- 419 + 31532489 = 31532908
- 431 + 31532477 = 31532908
- 479 + 31532429 = 31532908
Showing the first eight; more decompositions exist.
