Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8677240, here are decompositions:
- 17 + 8677223 = 8677240
- 59 + 8677181 = 8677240
- 101 + 8677139 = 8677240
- 113 + 8677127 = 8677240
- 197 + 8677043 = 8677240
- 269 + 8676971 = 8677240
- 347 + 8676893 = 8677240
- 419 + 8676821 = 8677240
Showing the first eight; more decompositions exist.
