Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76400, here are decompositions:
- 13 + 76387 = 76400
- 31 + 76369 = 76400
- 67 + 76333 = 76400
- 97 + 76303 = 76400
- 139 + 76261 = 76400
- 151 + 76249 = 76400
- 157 + 76243 = 76400
- 193 + 76207 = 76400
Showing the first eight; more decompositions exist.
