Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74540, here are decompositions:
- 13 + 74527 = 74540
- 19 + 74521 = 74540
- 31 + 74509 = 74540
- 127 + 74413 = 74540
- 157 + 74383 = 74540
- 163 + 74377 = 74540
- 223 + 74317 = 74540
- 229 + 74311 = 74540
Showing the first eight; more decompositions exist.
