Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529056, here are decompositions:
- 3 + 31529053 = 31529056
- 59 + 31528997 = 31529056
- 89 + 31528967 = 31529056
- 233 + 31528823 = 31529056
- 359 + 31528697 = 31529056
- 443 + 31528613 = 31529056
- 509 + 31528547 = 31529056
- 557 + 31528499 = 31529056
Showing the first eight; more decompositions exist.
