Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667420, here are decompositions:
- 7 + 8667413 = 8667420
- 17 + 8667403 = 8667420
- 43 + 8667377 = 8667420
- 71 + 8667349 = 8667420
- 101 + 8667319 = 8667420
- 107 + 8667313 = 8667420
- 131 + 8667289 = 8667420
- 149 + 8667271 = 8667420
Showing the first eight; more decompositions exist.
