Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537522, here are decompositions:
- 41 + 31537481 = 31537522
- 53 + 31537469 = 31537522
- 89 + 31537433 = 31537522
- 113 + 31537409 = 31537522
- 131 + 31537391 = 31537522
- 251 + 31537271 = 31537522
- 293 + 31537229 = 31537522
- 389 + 31537133 = 31537522
Showing the first eight; more decompositions exist.
