Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8735820, here are decompositions:
- 7 + 8735813 = 8735820
- 11 + 8735809 = 8735820
- 31 + 8735789 = 8735820
- 43 + 8735777 = 8735820
- 59 + 8735761 = 8735820
- 109 + 8735711 = 8735820
- 139 + 8735681 = 8735820
- 199 + 8735621 = 8735820
Showing the first eight; more decompositions exist.
