Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7564, here are decompositions:
- 3 + 7561 = 7564
- 5 + 7559 = 7564
- 17 + 7547 = 7564
- 23 + 7541 = 7564
- 41 + 7523 = 7564
- 47 + 7517 = 7564
- 83 + 7481 = 7564
- 107 + 7457 = 7564
Showing the first eight; more decompositions exist.
