Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532548, here are decompositions:
- 41 + 31532507 = 31532548
- 59 + 31532489 = 31532548
- 71 + 31532477 = 31532548
- 269 + 31532279 = 31532548
- 431 + 31532117 = 31532548
- 617 + 31531931 = 31532548
- 797 + 31531751 = 31532548
- 821 + 31531727 = 31532548
Showing the first eight; more decompositions exist.
