Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78810, here are decompositions:
- 7 + 78803 = 78810
- 13 + 78797 = 78810
- 19 + 78791 = 78810
- 23 + 78787 = 78810
- 29 + 78781 = 78810
- 31 + 78779 = 78810
- 73 + 78737 = 78810
- 89 + 78721 = 78810
Showing the first eight; more decompositions exist.
