Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529492, here are decompositions:
- 13 + 31529479 = 31529492
- 61 + 31529431 = 31529492
- 79 + 31529413 = 31529492
- 139 + 31529353 = 31529492
- 223 + 31529269 = 31529492
- 439 + 31529053 = 31529492
- 499 + 31528993 = 31529492
- 523 + 31528969 = 31529492
Showing the first eight; more decompositions exist.
