Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532862, here are decompositions:
- 29 + 31532833 = 31532862
- 113 + 31532749 = 31532862
- 223 + 31532639 = 31532862
- 269 + 31532593 = 31532862
- 281 + 31532581 = 31532862
- 311 + 31532551 = 31532862
- 373 + 31532489 = 31532862
- 433 + 31532429 = 31532862
Showing the first eight; more decompositions exist.
