Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528840, here are decompositions:
- 17 + 31528823 = 31528840
- 29 + 31528811 = 31528840
- 89 + 31528751 = 31528840
- 227 + 31528613 = 31528840
- 281 + 31528559 = 31528840
- 293 + 31528547 = 31528840
- 389 + 31528451 = 31528840
- 467 + 31528373 = 31528840
Showing the first eight; more decompositions exist.
