Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678016, here are decompositions:
- 5 + 8678011 = 8678016
- 23 + 8677993 = 8678016
- 37 + 8677979 = 8678016
- 257 + 8677759 = 8678016
- 293 + 8677723 = 8678016
- 353 + 8677663 = 8678016
- 409 + 8677607 = 8678016
- 439 + 8677577 = 8678016
Showing the first eight; more decompositions exist.
