Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573204, here are decompositions:
- 41 + 31573163 = 31573204
- 53 + 31573151 = 31573204
- 71 + 31573133 = 31573204
- 101 + 31573103 = 31573204
- 167 + 31573037 = 31573204
- 197 + 31573007 = 31573204
- 233 + 31572971 = 31573204
- 263 + 31572941 = 31573204
Showing the first eight; more decompositions exist.
