Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23520, here are decompositions:
- 11 + 23509 = 23520
- 23 + 23497 = 23520
- 47 + 23473 = 23520
- 61 + 23459 = 23520
- 73 + 23447 = 23520
- 89 + 23431 = 23520
- 103 + 23417 = 23520
- 149 + 23371 = 23520
Showing the first eight; more decompositions exist.
