Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489444, here are decompositions:
- 11 + 31489433 = 31489444
- 17 + 31489427 = 31489444
- 53 + 31489391 = 31489444
- 197 + 31489247 = 31489444
- 227 + 31489217 = 31489444
- 251 + 31489193 = 31489444
- 263 + 31489181 = 31489444
- 347 + 31489097 = 31489444
Showing the first eight; more decompositions exist.
