Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 477888, here are decompositions:
- 7 + 477881 = 477888
- 31 + 477857 = 477888
- 41 + 477847 = 477888
- 67 + 477821 = 477888
- 79 + 477809 = 477888
- 97 + 477791 = 477888
- 149 + 477739 = 477888
- 157 + 477731 = 477888
Showing the first eight; more decompositions exist.
