Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478816, here are decompositions:
- 3 + 478813 = 478816
- 5 + 478811 = 478816
- 29 + 478787 = 478816
- 47 + 478769 = 478816
- 53 + 478763 = 478816
- 89 + 478727 = 478816
- 137 + 478679 = 478816
- 179 + 478637 = 478816
Showing the first eight; more decompositions exist.
