Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533512, here are decompositions:
- 13 + 31533499 = 31533512
- 61 + 31533451 = 31533512
- 103 + 31533409 = 31533512
- 379 + 31533133 = 31533512
- 421 + 31533091 = 31533512
- 499 + 31533013 = 31533512
- 541 + 31532971 = 31533512
- 613 + 31532899 = 31533512
Showing the first eight; more decompositions exist.
