Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99400, here are decompositions:
- 3 + 99397 = 99400
- 23 + 99377 = 99400
- 29 + 99371 = 99400
- 53 + 99347 = 99400
- 83 + 99317 = 99400
- 149 + 99251 = 99400
- 167 + 99233 = 99400
- 227 + 99173 = 99400
Showing the first eight; more decompositions exist.
