Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529276, here are decompositions:
- 3 + 31529273 = 31529276
- 7 + 31529269 = 31529276
- 19 + 31529257 = 31529276
- 109 + 31529167 = 31529276
- 127 + 31529149 = 31529276
- 223 + 31529053 = 31529276
- 283 + 31528993 = 31529276
- 307 + 31528969 = 31529276
Showing the first eight; more decompositions exist.
