Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 88400, here are decompositions:
- 3 + 88397 = 88400
- 61 + 88339 = 88400
- 73 + 88327 = 88400
- 79 + 88321 = 88400
- 139 + 88261 = 88400
- 163 + 88237 = 88400
- 223 + 88177 = 88400
- 271 + 88129 = 88400
Showing the first eight; more decompositions exist.
