Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700784, here are decompositions:
- 11 + 8700773 = 8700784
- 17 + 8700767 = 8700784
- 263 + 8700521 = 8700784
- 311 + 8700473 = 8700784
- 317 + 8700467 = 8700784
- 353 + 8700431 = 8700784
- 383 + 8700401 = 8700784
- 401 + 8700383 = 8700784
Showing the first eight; more decompositions exist.
