Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8677642, here are decompositions:
- 89 + 8677553 = 8677642
- 131 + 8677511 = 8677642
- 251 + 8677391 = 8677642
- 353 + 8677289 = 8677642
- 359 + 8677283 = 8677642
- 419 + 8677223 = 8677642
- 461 + 8677181 = 8677642
- 503 + 8677139 = 8677642
Showing the first eight; more decompositions exist.
