Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537836, here are decompositions:
- 13 + 31537823 = 31537836
- 89 + 31537747 = 31537836
- 149 + 31537687 = 31537836
- 227 + 31537609 = 31537836
- 233 + 31537603 = 31537836
- 263 + 31537573 = 31537836
- 277 + 31537559 = 31537836
- 293 + 31537543 = 31537836
Showing the first eight; more decompositions exist.
