Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74400, here are decompositions:
- 17 + 74383 = 74400
- 19 + 74381 = 74400
- 23 + 74377 = 74400
- 37 + 74363 = 74400
- 43 + 74357 = 74400
- 47 + 74353 = 74400
- 83 + 74317 = 74400
- 89 + 74311 = 74400
Showing the first eight; more decompositions exist.
