Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8677620, here are decompositions:
- 13 + 8677607 = 8677620
- 43 + 8677577 = 8677620
- 67 + 8677553 = 8677620
- 109 + 8677511 = 8677620
- 137 + 8677483 = 8677620
- 139 + 8677481 = 8677620
- 163 + 8677457 = 8677620
- 167 + 8677453 = 8677620
Showing the first eight; more decompositions exist.
