Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8942, here are decompositions:
- 13 + 8929 = 8942
- 19 + 8923 = 8942
- 79 + 8863 = 8942
- 103 + 8839 = 8942
- 139 + 8803 = 8942
- 163 + 8779 = 8942
- 181 + 8761 = 8942
- 211 + 8731 = 8942
Showing the first eight; more decompositions exist.
