Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548624, here are decompositions:
- 5 + 31548619 = 31548624
- 11 + 31548613 = 31548624
- 31 + 31548593 = 31548624
- 47 + 31548577 = 31548624
- 61 + 31548563 = 31548624
- 73 + 31548551 = 31548624
- 97 + 31548527 = 31548624
- 103 + 31548521 = 31548624
Showing the first eight; more decompositions exist.
