Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748420, here are decompositions:
- 7 + 8748413 = 8748420
- 17 + 8748403 = 8748420
- 53 + 8748367 = 8748420
- 59 + 8748361 = 8748420
- 61 + 8748359 = 8748420
- 89 + 8748331 = 8748420
- 97 + 8748323 = 8748420
- 139 + 8748281 = 8748420
Showing the first eight; more decompositions exist.
