Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528808, here are decompositions:
- 7 + 31528801 = 31528808
- 67 + 31528741 = 31528808
- 79 + 31528729 = 31528808
- 139 + 31528669 = 31528808
- 229 + 31528579 = 31528808
- 277 + 31528531 = 31528808
- 307 + 31528501 = 31528808
- 349 + 31528459 = 31528808
Showing the first eight; more decompositions exist.
