Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8677728, here are decompositions:
- 5 + 8677723 = 8677728
- 47 + 8677681 = 8677728
- 151 + 8677577 = 8677728
- 251 + 8677477 = 8677728
- 271 + 8677457 = 8677728
- 331 + 8677397 = 8677728
- 337 + 8677391 = 8677728
- 431 + 8677297 = 8677728
Showing the first eight; more decompositions exist.
