Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489516, here are decompositions:
- 53 + 31489463 = 31489516
- 83 + 31489433 = 31489516
- 89 + 31489427 = 31489516
- 167 + 31489349 = 31489516
- 257 + 31489259 = 31489516
- 269 + 31489247 = 31489516
- 347 + 31489169 = 31489516
- 419 + 31489097 = 31489516
Showing the first eight; more decompositions exist.
