Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623480, here are decompositions:
- 19 + 31623461 = 31623480
- 37 + 31623443 = 31623480
- 41 + 31623439 = 31623480
- 59 + 31623421 = 31623480
- 103 + 31623377 = 31623480
- 107 + 31623373 = 31623480
- 137 + 31623343 = 31623480
- 223 + 31623257 = 31623480
Showing the first eight; more decompositions exist.
