Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671782, here are decompositions:
- 13 + 8671769 = 8671782
- 43 + 8671739 = 8671782
- 61 + 8671721 = 8671782
- 71 + 8671711 = 8671782
- 73 + 8671709 = 8671782
- 113 + 8671669 = 8671782
- 149 + 8671633 = 8671782
- 151 + 8671631 = 8671782
Showing the first eight; more decompositions exist.
