Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529498, here are decompositions:
- 19 + 31529479 = 31529498
- 67 + 31529431 = 31529498
- 139 + 31529359 = 31529498
- 151 + 31529347 = 31529498
- 229 + 31529269 = 31529498
- 241 + 31529257 = 31529498
- 331 + 31529167 = 31529498
- 349 + 31529149 = 31529498
Showing the first eight; more decompositions exist.
