Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38400, here are decompositions:
- 7 + 38393 = 38400
- 23 + 38377 = 38400
- 29 + 38371 = 38400
- 67 + 38333 = 38400
- 71 + 38329 = 38400
- 73 + 38327 = 38400
- 79 + 38321 = 38400
- 83 + 38317 = 38400
Showing the first eight; more decompositions exist.
