Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537774, here are decompositions:
- 53 + 31537721 = 31537774
- 83 + 31537691 = 31537774
- 227 + 31537547 = 31537774
- 293 + 31537481 = 31537774
- 383 + 31537391 = 31537774
- 461 + 31537313 = 31537774
- 467 + 31537307 = 31537774
- 503 + 31537271 = 31537774
Showing the first eight; more decompositions exist.
