Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478782, here are decompositions:
- 13 + 478769 = 478782
- 19 + 478763 = 478782
- 41 + 478741 = 478782
- 43 + 478739 = 478782
- 53 + 478729 = 478782
- 71 + 478711 = 478782
- 103 + 478679 = 478782
- 131 + 478651 = 478782
Showing the first eight; more decompositions exist.
