Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8677440, here are decompositions:
- 41 + 8677399 = 8677440
- 43 + 8677397 = 8677440
- 47 + 8677393 = 8677440
- 53 + 8677387 = 8677440
- 73 + 8677367 = 8677440
- 97 + 8677343 = 8677440
- 151 + 8677289 = 8677440
- 157 + 8677283 = 8677440
Showing the first eight; more decompositions exist.
