Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667142, here are decompositions:
- 5 + 8667137 = 8667142
- 149 + 8666993 = 8667142
- 251 + 8666891 = 8667142
- 293 + 8666849 = 8667142
- 359 + 8666783 = 8667142
- 431 + 8666711 = 8667142
- 461 + 8666681 = 8667142
- 599 + 8666543 = 8667142
Showing the first eight; more decompositions exist.
