Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548328, here are decompositions:
- 5 + 31548323 = 31548328
- 29 + 31548299 = 31548328
- 41 + 31548287 = 31548328
- 47 + 31548281 = 31548328
- 59 + 31548269 = 31548328
- 179 + 31548149 = 31548328
- 281 + 31548047 = 31548328
- 311 + 31548017 = 31548328
Showing the first eight; more decompositions exist.
