Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23490, here are decompositions:
- 17 + 23473 = 23490
- 31 + 23459 = 23490
- 43 + 23447 = 23490
- 59 + 23431 = 23490
- 73 + 23417 = 23490
- 151 + 23339 = 23490
- 157 + 23333 = 23490
- 163 + 23327 = 23490
Showing the first eight; more decompositions exist.
