Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548888, here are decompositions:
- 17 + 31548871 = 31548888
- 31 + 31548857 = 31548888
- 71 + 31548817 = 31548888
- 131 + 31548757 = 31548888
- 139 + 31548749 = 31548888
- 149 + 31548739 = 31548888
- 191 + 31548697 = 31548888
- 211 + 31548677 = 31548888
Showing the first eight; more decompositions exist.
