Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668140, here are decompositions:
- 7 + 8668133 = 8668140
- 29 + 8668111 = 8668140
- 59 + 8668081 = 8668140
- 67 + 8668073 = 8668140
- 73 + 8668067 = 8668140
- 79 + 8668061 = 8668140
- 83 + 8668057 = 8668140
- 97 + 8668043 = 8668140
Showing the first eight; more decompositions exist.
