Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548474, here are decompositions:
- 7 + 31548467 = 31548474
- 31 + 31548443 = 31548474
- 43 + 31548431 = 31548474
- 47 + 31548427 = 31548474
- 73 + 31548401 = 31548474
- 131 + 31548343 = 31548474
- 151 + 31548323 = 31548474
- 173 + 31548301 = 31548474
Showing the first eight; more decompositions exist.
