Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536528, here are decompositions:
- 7 + 31536521 = 31536528
- 29 + 31536499 = 31536528
- 47 + 31536481 = 31536528
- 131 + 31536397 = 31536528
- 137 + 31536391 = 31536528
- 167 + 31536361 = 31536528
- 181 + 31536347 = 31536528
- 241 + 31536287 = 31536528
Showing the first eight; more decompositions exist.
