Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478918, here are decompositions:
- 5 + 478913 = 478918
- 17 + 478901 = 478918
- 47 + 478871 = 478918
- 107 + 478811 = 478918
- 131 + 478787 = 478918
- 149 + 478769 = 478918
- 179 + 478739 = 478918
- 191 + 478727 = 478918
Showing the first eight; more decompositions exist.
