Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668242, here are decompositions:
- 41 + 8668201 = 8668242
- 101 + 8668141 = 8668242
- 109 + 8668133 = 8668242
- 131 + 8668111 = 8668242
- 179 + 8668063 = 8668242
- 181 + 8668061 = 8668242
- 199 + 8668043 = 8668242
- 211 + 8668031 = 8668242
Showing the first eight; more decompositions exist.
