Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548432, here are decompositions:
- 5 + 31548427 = 31548432
- 31 + 31548401 = 31548432
- 89 + 31548343 = 31548432
- 101 + 31548331 = 31548432
- 109 + 31548323 = 31548432
- 131 + 31548301 = 31548432
- 151 + 31548281 = 31548432
- 163 + 31548269 = 31548432
Showing the first eight; more decompositions exist.
