Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543486, here are decompositions:
- 5 + 31543481 = 31543486
- 89 + 31543397 = 31543486
- 137 + 31543349 = 31543486
- 263 + 31543223 = 31543486
- 269 + 31543217 = 31543486
- 353 + 31543133 = 31543486
- 383 + 31543103 = 31543486
- 419 + 31543067 = 31543486
Showing the first eight; more decompositions exist.
