Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532344, here are decompositions:
- 3 + 31532341 = 31532344
- 5 + 31532339 = 31532344
- 83 + 31532261 = 31532344
- 227 + 31532117 = 31532344
- 281 + 31532063 = 31532344
- 461 + 31531883 = 31532344
- 593 + 31531751 = 31532344
- 617 + 31531727 = 31532344
Showing the first eight; more decompositions exist.
