Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667428, here are decompositions:
- 79 + 8667349 = 8667428
- 109 + 8667319 = 8667428
- 127 + 8667301 = 8667428
- 139 + 8667289 = 8667428
- 157 + 8667271 = 8667428
- 277 + 8667151 = 8667428
- 307 + 8667121 = 8667428
- 349 + 8667079 = 8667428
Showing the first eight; more decompositions exist.
