Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532620, here are decompositions:
- 23 + 31532597 = 31532620
- 47 + 31532573 = 31532620
- 113 + 31532507 = 31532620
- 131 + 31532489 = 31532620
- 191 + 31532429 = 31532620
- 281 + 31532339 = 31532620
- 359 + 31532261 = 31532620
- 401 + 31532219 = 31532620
Showing the first eight; more decompositions exist.
