Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689040, here are decompositions:
- 7 + 8689033 = 8689040
- 43 + 8688997 = 8689040
- 79 + 8688961 = 8689040
- 97 + 8688943 = 8689040
- 211 + 8688829 = 8689040
- 223 + 8688817 = 8689040
- 337 + 8688703 = 8689040
- 433 + 8688607 = 8689040
Showing the first eight; more decompositions exist.
