Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542052, here are decompositions:
- 29 + 31542023 = 31542052
- 41 + 31542011 = 31542052
- 71 + 31541981 = 31542052
- 149 + 31541903 = 31542052
- 359 + 31541693 = 31542052
- 401 + 31541651 = 31542052
- 419 + 31541633 = 31542052
- 461 + 31541591 = 31542052
Showing the first eight; more decompositions exist.
