Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7464, here are decompositions:
- 5 + 7459 = 7464
- 7 + 7457 = 7464
- 13 + 7451 = 7464
- 31 + 7433 = 7464
- 47 + 7417 = 7464
- 53 + 7411 = 7464
- 71 + 7393 = 7464
- 113 + 7351 = 7464
Showing the first eight; more decompositions exist.
