Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554244, here are decompositions:
- 3 + 31554241 = 31554244
- 83 + 31554161 = 31554244
- 101 + 31554143 = 31554244
- 167 + 31554077 = 31554244
- 233 + 31554011 = 31554244
- 251 + 31553993 = 31554244
- 257 + 31553987 = 31554244
- 443 + 31553801 = 31554244
Showing the first eight; more decompositions exist.
