Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537404, here are decompositions:
- 13 + 31537391 = 31537404
- 97 + 31537307 = 31537404
- 131 + 31537273 = 31537404
- 137 + 31537267 = 31537404
- 181 + 31537223 = 31537404
- 251 + 31537153 = 31537404
- 257 + 31537147 = 31537404
- 271 + 31537133 = 31537404
Showing the first eight; more decompositions exist.
