Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104208, here are decompositions:
- 29 + 104179 = 104208
- 47 + 104161 = 104208
- 59 + 104149 = 104208
- 61 + 104147 = 104208
- 89 + 104119 = 104208
- 101 + 104107 = 104208
- 149 + 104059 = 104208
- 199 + 104009 = 104208
Showing the first eight; more decompositions exist.
