Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603000, here are decompositions:
- 41 + 31602959 = 31603000
- 83 + 31602917 = 31603000
- 101 + 31602899 = 31603000
- 137 + 31602863 = 31603000
- 197 + 31602803 = 31603000
- 311 + 31602689 = 31603000
- 353 + 31602647 = 31603000
- 419 + 31602581 = 31603000
Showing the first eight; more decompositions exist.
