Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537624, here are decompositions:
- 191 + 31537433 = 31537624
- 233 + 31537391 = 31537624
- 311 + 31537313 = 31537624
- 317 + 31537307 = 31537624
- 353 + 31537271 = 31537624
- 401 + 31537223 = 31537624
- 491 + 31537133 = 31537624
- 641 + 31536983 = 31537624
Showing the first eight; more decompositions exist.
