Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104280, here are decompositions:
- 37 + 104243 = 104280
- 41 + 104239 = 104280
- 47 + 104233 = 104280
- 73 + 104207 = 104280
- 97 + 104183 = 104280
- 101 + 104179 = 104280
- 107 + 104173 = 104280
- 131 + 104149 = 104280
Showing the first eight; more decompositions exist.
