Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529548, here are decompositions:
- 41 + 31529507 = 31529548
- 101 + 31529447 = 31529548
- 227 + 31529321 = 31529548
- 269 + 31529279 = 31529548
- 461 + 31529087 = 31529548
- 467 + 31529081 = 31529548
- 797 + 31528751 = 31529548
- 1049 + 31528499 = 31529548
Showing the first eight; more decompositions exist.
